S14 Idle problems

[Djinfinit]

Hey guys, im having a problem with my s14 ka24de 1995 AUTO:(. It starts up fine cold, hot, or warm, but after its at operating temperature it just goes mad. Idle bounces, car stumbles backfires, or misfires not sure which one, and if your sitting in it its the worst ride ever in park. Now ive taken out the ecu to check for codes, so its on the passenger floor, but no codes. Im really lost as to what is causing this problem. Also if you put the car in gear its fine once again, problem only occurs in park, or neutral.

If someone will please watch this lenghty video of my car, and inform me of what might be causing the problems it will be much appreciated. Dont be afraid to guess. either:)

Good news.. took it for the first run after winter, today(canada). And all the problems vanished.

I noticed in your vid u say no check engine light..pull ecu anyway as described on ka24development.com I'm having problems with mine now and then..a 95 auto aswell. I had a code 34 (knock sensor) when I put the ecu in diagnostic mode...had I not done that on assumption something was wrong I would have never none the code was there. Why? Evidently obd1 cars don't emit a check engine light for some codes like 34. Also how old r plugs and wires.

Wish i could think/knew of more things to check that are definite possibilities. Good luck..I know your frustration lol

Also maybe try cleaning IACV with intake cleaner:
