I'm currently having the same problem, I'm going to adjust my Idle screw again and if that fixs it i'll let you know.

Okay I fixed my issue, So here is how you do it.

1. Start your car.
2. Listen to your idle for a little while.
3. You will need to disconnect the power from the IAC, *it will be a cable right behind your intake, it actually hooks in to the intake manifold*
4. After doing so, Adjust the Idle screw, *it will be a flat head screw right above your throttle body I believe.*
5. Adjust it till your idle is about 50+ above what you want.
6. Plug the cable back in, and let the car run for like 2-5 minutes.
7. Turn off car and restart. Should be fine.


Hope this helps you out a bit, If you need more I'll try and get pictures later.

You will need a priest and a lot of holy water to fix this problem.

what is the iacv

Idle Air Control Valve. Mine tore open and caused my car to have the same problem (and overheat, too), except since my car idles really low, my car jumped from 600rpm-1700rpm.

mine never overheated even when i blew the head gasket lol

i just adjusted the idle down on my 3g .. on my civic i cleaned the iacv and that fixed it same with my 4th gen but then my 4th gens started acting up again lol so i adjusted the idle down so i no longer have a cold idle lol always just at 900ish
