I have a 91 teg auto and I have a accel problem and missfire soft pop out muffler at idel . At low accel ( about 30 to 50 mph) my car jerks or is sluggish and happens when I try to stay one speed . When I floor it. It is fine . I rebuilt the b18a1 , new plugs , time belt , water pump , cap , rotor, main fuel relay, cleand iacv and throt body , checked tps got 5v and its ok
it started after a cv axel bust and replaced it and new tranny fluid , no flush thoe .
Is it a tcu or ecu or egr or tranny . I had a shop look at it they didn't know
I need help !!! HELP ME

So everything ran fine before the axle replacement? If it only started after the work you did, chances are you messed something up. Are there any CEL's? Does the car idle normal? Does the problem only happen between 30-50 mph?
How exactly did you change the fluid? Since no flush, I'm assuming you just used the drain plug. How did the old fluid look? How much fluid did you add?

Did you ever disconnect anything (harness plugs, vacuum lines, etc)?

Before the axel the s3 light flashed on the dash and the tranny wouldn't shift and car would start and die . Its more notesable at 40 mph . On the tranny fluid when I pulled cv axel . The fluid fell out and I toped the tranny fluid off when new axel was in . Then this problem with jerkin sluggish started so I draned tranny and refilled it 3.3qt dex 3 what the book said
Yes I had a lot of vacume hoses taken off to clean throt body and iacv . I cleaned them when I was getting a rough idel and that has stopeiid some . The problem with the sluggish started after the fluid and axel change . Tranny shop said it what normal , ya right .

No cel lights and idel is rough I starts off at 2500 k and drops to 700 and when I stop and idel it drops realy low almost die and I gas it to stay alive

Tranny fluid was like new when axel was pulled and I drove about 10k sence I got it
Drain plug change.

I dont think you have a problem with your tranny OMP...I think ur problem is more on the engine itself...Is almost seems like ur car is running rich or lean...Its normal when ur idle and you have ur car in gear or drive..tranny puts load on the engine and tends to lower ur idle...u have to adjust something to make it idle at normal like 800 or so...could be timing or something...but thats my omp..

Should I get a ecu used one, now that u say that my gas milage is down , I did seafoam the car in vacum line and gas , but how would I check the rich or lean gas.

did you full sweep the tps when you checked it? sometimes that can devlop dead spots

acura1987

no because it is rivited to the throt body. The shop I had look at the car said it was good can't without the throt body to , that's y I cleaned it . I didn't like the way the shop was to me so is that true about the tps . Or is there a way to remove the tps .

A low RPM misfire usually indicates clogged EGR ports. The '90-93 Integra automatic did have an EGR system; I'd check the ports and clean them as necessary.
