*Ok so I did notice while on the hwy, at around 70mph or so with a steady foot and with flat road it felt like the car was maybe loosing power but if I moved the throttle any, it seemed to be normal. Could just be paranoid. Not sure.


The Integra looks like the '90-'91 version. It has the Acura badge on the hood which was added for '91 but it has the '90 trunk lid with the big decal and it looks differently faded from the rest of the car. Something happened at some point. It's not clear in the photos that it has the moonroof confirming it to be a GS but if it is it would be Melbourne Blue Metallic. The next closest color might be Superior Blue Metallic on the RS sedan. The white, black, and red GS sedans were much more common. That's a rare Integra and that color was rare even on the other Integra it was available on, the GS 3dr hatch. Old cars are always interesting.

Did you say at one point that you replaced the throttle position sensor? A minor throttle change, either increasing or decreasing throttle, resulting in an instant change in power isn't a fuel system clog problem.

I've forgotten some of the windshield wiper control discussion. Is the circuit we were discussing built into the ECU? I think I'd get some opinions from the Acura dealership techs on that problem. Whether they have a clue about it anyone's guess though. The two known problems are the wipers work at only the fast speed and the engine dogs out at high RPMs. I wonder if dry solder connections in the ECU are causing both problems.

A second thought is that talk here of the dual-stage intake manifold now makes me curious if the leaning out of the A-F ratio happens at about the RPM of the intake change. I have zero experience with such intakes though.

No sunroof on that teg, or any door handles! It's been through it I'm guessing.


Regarding the dual plenum intake, all it does is change the pulse wave length between two different length and diameter runners to better the ram air effect at higher rpm. I'm not aware of the ECU adding fuel or change the injector pulse widths at that transition. Maybe something to look into the future with if nothing else fixes the problem. A quick check to rule that out would be to pull the vacuum hose to the butterfly actuator and see if the problem persists.

Also about the TPS, the new intake manifold is using the new throttle body and TPS that came off of it (112K miles). Not sure how likely it is for that TPS to also be faulty. If it comes down to a TPS signal related cause I will have to first rule out the ECU to ensure it's not the ECU misinterpreting data.


Going back the wipers. The dealer found no power between the under hood fuse box (next to battery) and the wiper relay (between radiator fans) and are going to check the wire harness for melted or cut wires. It's not going to be cheap but I need them fixed, so I'll cough. I pray they get them fixed!

In the meantime they gave me a 2019 TLX 2.4 Tech to ride around in. This dealer is great. Last minute scheduling, loaner for a non recall related service (hell, a loaner for a 23 year old car) and extremely friendly staff. The techs and service advisers are cool too and listen to whatever concerns I bring up about the car.

I mentioned the sputter I felt on the hwy this morning to them and asked if they had time to check the fuel pressure and they added to the service, late notice.


The power issue did not happen at this speed or rpm. I noticed the issue after about 30 minutes into the drive (all hwy) where traffic slowed to about 65-70 and kept slowing between those speeds.

It looks like you have some pretty fast moving traffic in North Carolina, since you are cruising along at 92!

Morning traffic: Everyone drives 80+.

Afternoon traffic: everyone drives 60 or below.

Night traffic: Everyone drives 80+ AND weaves in and out of lanes.


Lol On my way home from the dealer with the TLX I saw four state troopers with cars pulled over, on my way to pick up the Vigor I saw two, and on my way home again I saw one. They were out today more than usual. Must because they knew I was doing 92 earlier!




Got my car back around 4pm, they fixed the wipers! Problem ended up being the under hood fuse box. The prong that the 30am wiper circuit fuse makes contact with was broken. They were able to fix it, now they work beautifully!

My service adviser was a champ. And the tech who worked on my car as well. He's one of the older guys who has seen some stuff. They wold me a few weeks ago they completely re-wired a 92 Legend for a customer to give to his son. They pulled up pictures of the customers car to show me the wiring mess. Amazing dealership honestly, most places I feel like wouldn't touch it.


The same tech turned his attention back to my car and questioned how I managed the 5 lug hub swap, RL brake calipers and what it was lowered on. I think he liked it a lot. They said this is the first Vigor they have seen come through in several years. I'm sure they'll remember this one!

I go back Monday to start the diagnoses of the bogging. I showed the tech a few clips of the issue and told him all the parts that have been replaced. Mentioned I have a back up ECU to swap out, he said the current one installed could have a leaking capacitor and since the issue is only present after driving for some time it is likely due to heat expansion inside the ECU from operation/ run time and then that's when the issue arises. He's not sure about it being fuel pressure, he mentioned it could be pulling timing since the pattern is so distinct. I had never considered that before but it makes total sense. Low fuel pressure could but really isn't likely to be that persistent with the bogging.


Before I left the dealer I picked up 3qts of MTF for half price. Parts department told me they never sell the stuff anymore and only keep 7 qts in stock now.

Tomorrow I'll swap ECU's, swap in MTF and probably hollow out the catalytic converter then get some exhaust work done.


Checked fluids when I got home. Oil is clean and at the same level as before, no milky residue under valve cover cap, PS fluid the same, everything. Though the coolant reservoir is lower again but I can't see where or if there is a leak this time. Still no smoke or anything coming from the exhaust and it smells about like the TSXs. Maybe the coolant just leveled itself out. I'll keep an eye on it.

So happy that this is moving along and so positively!

Actually, the leaky cap thing is entirely plausible.

I had that broken fuse box connector thing on an Escort van years ago; took out the wipers and half the lights.

Good call with your saying it could have been damage at the underside of the fuse panel.

If the Vigor's ECU were a 1970s solid state Hi-Fi amp, a complete recap would be a given.

Talked with a Honda ECU specialist. He said it's unlikely that a cap is going since " Honda doesnt use electrolytic capacitors in their ecus.". He's repaired may be 3 out of the hundreds he's chipped and the repairs were bad chipsets. Still. The Vigor coukd have a bad ECU in one of those days I guess.

He recommended me to test and see if the cat is clogged.

Wow, that's interesting. So no caps which dry out by maybe IC chips which can fail. I would think a clogged converter would trigger a CEL but maybe not?

The tuner IC chip which failed in the high end Pioneer receiver I bought in the '80s hasn't been available for a couple of decades now so I'm left with a mid-grade integrated amp which I can't bring myself to recycle.

On modern OBDII cars it would cause a CEL, but on OBDI cars that have just one O2 sensor, up stream from the cat, the ECU knows no different.

This story has been pretty inspiring to me.

When I was a teenager and in my early 20s, I wanted a Prelude so bad. After my Integra was stolen and stripped, I purchased a 98 SH and the ownership experience was nothing short of a disaster. I eventually sold it for a Mazda 3, which was also a disaster, and then got a RAV4 V6 that my wife drove for 10 years.

So, here I am, fast approaching 40 and I want to give a Prelude, some H22 model, a run again. Having experienced NSXs, S2000s, Sis, Integras, and the lot...the VTEC sound in the H22 was (to me) by far the greatest of the Hondas I have experienced.

I think it would be a cool project with my kids, particularly my son who will be needing something to set his mind on soon. I have a 65 Mustang 289 already in the backyard that needs a full restoration...but I'd love to add a Prelude to it as well...and an ITR as my 2nd choice.

It is also not a bad way to get into a fun car, as my real first dollars need to go to the family and chore transportation.

Ok! Swapped ECU and got a used Denso MAP sensor off a Legend. Car started and ran completely fine, like normal. Pulled out of driveway after letting it warm up for about 10 minutes so I can defrost. Easy, slow acceleration. Got into 3rd and right as I was letting out of the clutch, getting onto the gas it fell on it's face with no power until I let off the gas and power came back if I slowly reapplied throttle.

Gas gauge shows has a quarter of a tank to E....

I fill it up. Shell 93 always.

Drive around in the city for about 10 minutes, issue free, drive country back roads, issue free. Never had any issues idling down from crusing rpms or while coasting to a stop like before or accelerating after making a turn (intersection). Still bogs under WOT above, around 4,000rpm or higher.


Now thatch with a full tank seems like it can putt putt around town fine and drive gently around back roads (twists and hills).



To me it almost sounds like two separate fuel delivery issues.

Issue one seems to be low rpm primarily: coasting, exiting corner= bogging. But not idling or revving in neutral. Problem occurs only at half tank or below it seems like. Caused by misaligned fuel pump pick up in gas tank/ pick up not reaching fuel adequately?

Issue two seems to be with high rpm or WOT. Problem occurs with or without full tank. Usually around 4,000rpm and above. Acceleration is strong with initial throttle tip in and then sometimes immediately or gradually looses all power after rpms climb a grand or so, feels like turning off the fuel. Caused by faulty Fuel Pressure Regulator? Not able to keep adequate fuel pressure with a high injector duty?

I haven't read this tread fully but anytime I have had serious bogging patterns with my Honda cars it's always been TPS or MAP sensor.

Starting to like having a new car without the new car payment. Hideous and cheap interior but it does drive half decent and looks really good inside at night with the ambient lighting. Not impressed by the Jewel Eye headlights output compared to the TSX's Osram CBI's. I do love the smooth, quiet ride, 4WS and the ELS. The driving assistance stuff is cool, okay, but eh. Not a $43,000 car IMO, especially with the 4 cylinder. Love Still Night Pearl though, and the red is a bit too much but it's different in a good way and I'm starting to not mind it as much. I probably would have gotten Umber if it was available still.


Anyway, I'm calling Acura tomorrow and going to ask for an update on the Vigor. I haven't heard anything yet and it's going on 4 days now.

Car is back. Problem is not fixed. The tech did notice the dual plenum arm was bent so he bent it back in place and said on the test drive the issue was fixed.... yeah no on the hwy going home it was not fixed.

Engine power coming off and on while in 4th around 4,000rpm merging...Drove it home with as light throttle as possible and the few times I did lay into it the problem was back.


I picked up the newer FPR from the shop that replaced the engine and I'll get it swapped over tomorrow and hope it fixes the problem.

Eben though the dealer had my car for four days and said the issue was fixed and it is not, I do not feel like going back and continuing to drive the car if it's running mostly lean. I have a feeling that's what weakened the valve on my old engine.

Car is back. Problem is not fixed. The tech did notice the dual plenum arm was bent so he bent it back in place and said on the test drive the issue was fixed.... yeah no on the hwy going home it was not fixed.

Engine power coming off and on while in 4th around 4,000rpm merging...Drove it home with as light throttle as possible and the few times I did lay into it the problem was back.


I picked up the newer FPR from the shop that replaced the engine and I'll get it swapped over tomorrow and hope it fixes the problem.

Eben though the dealer had my car for four days and said the issue was fixed and it is not, I do not feel like going back and continuing to drive the car if it's running mostly lean. I have a feeling that's what weakened the valve on my old engine.


Could there be some residual sludge in the fuel tank being picked up?
A lot of time with older cars that have been sitting, the fuel tank and filter needs to be cleaned out.

Getting really stressed out over this issue. Stalled at a light today and the battery light along with the oil light started flashing quickly. Started engine and battery light goes away but oil light remains a slow blink.

Take key out of ignition and restart it and no lights. No CEL. All this with the new ECU.



Went around smacking, tugging and wiggling all the wires around the car that I could. Even whacked the EGR and IACV for a minute and idle wasn't affected.




Issue seems to be worse with it being below half tank. Did Acura, Honda or independent Honda shop remove tank and inspect fuel pump like I asked? No. Did they monitor fuel trim/ ignition pulses like I asked? No.

I'm losing it guys. Roughly 10 days away from the track event. :(

So the car runs fine albeit at lower speeds when the gas tank is full? That would be important.

I dunno, kinda sounds like a tri-shaft bearing.

It's the Bleek-Grunz converter. Probably.

It's not normally too hard to pull out the fuel pump and lose the filter. Just don't smoke whilst you're doing it.

Does sound more like an electrickery issue, though. Have you ever changed the main relay, or is that the only original part of the first car you bought?

Guess who just learned his car DOES have an ignition ignitor.... Found it under "battery" on Acura part sites.

Never saw one pop up on rock auto or ebay when replacing the Ignition system so I assumed it was controlled by the ECM or Coil.


This scanner danner video is pretty reassuring it could be my ignitor, which is original and also discontinued.

Might grab one off a 2.5TL. The 94 Vigor and 95+ 2.5 TL have the same part number but 92-93 Vigor is with 88-90 Legend.

Are you 100% sure the timing is right?

My mom's 2014 Accord just had the timing chain stretch and it caused very similar symptoms (multiple times).

It's a long shot, I know...

What sort of track event are we talking about?
