Well I cleared all the codes from my car, fixed their issues, w/e. All rock solid, vtec works great, yada yada.

I already had a surging idle that came and went but I threw no code for it. Then I started throwing the code for IACV intermittently, didn't affect anything, just came and went and had a surging idle here and there.

Now this morning my car throws IACV code at startup, idles solid no matter what, but under load it is giving fuel in an on/off fashion until I increase throttle in which it clears up and jumps in rpms.

I can drive but I gotta get on it and stay on the gas. If I left off and back on, the motor kinda jumps, but runs fine if I'm giving gas.

Now I've completely cleaned the IACV and FITV, even replaced the IACV with a newer one just as clean and I get the same things.

Checked for vacuum leaks and any other plugs not hooked up, all solid. I've tried jumping the plug on the harness and still no dice.

I tried tapping my ECU slightly and it deff gave the motor a miss when I hit it, in no way did I hit it hard lol just a friendly slap like what up hoe

Maybe bad ECU then?



I'm fucking clueless as to what the fuck happened while I was asleep to make this problem arise. I reset the ecu over and over hoping I will start it and it'll be straight but to no avail...

Help ploxkthx

I had an IACV problem and i cleaned it. It works better alot better now, but i think i still need to replace it.

But i did have the same issue where i had to keep giving it gas to stay alive. I dont think your 2nd IACV is bad thats just terrible luck if it is.

Naw I fixed my problem.

I still throw the code for it, and idle isn't perfect, but I swear its getting better now.

Lose connector was what was fuckin me up.
