Idle prob

[m3kidds]

I just adjusted my valve clearance and now my idle is around 200-300 and it stutters when cold. But when it get really warmed up it goes back to 700. Any ideas? Car works great after the valve adjustment in terms of pickup and performance, except for the idling.

check the idle air control valve

[SenseiAccord]

idling at 200-300 RPMs is i think impossible. But yea check the idle air control valve. Adjust it and see if it makes a difference.

[m3kidds]

Yeh its possible cuz its just above "0" and it cut off once at a stoplight. once it gets really hot, it goes back to normal about 700. where is the idle air control valve?

[mechy1barry]

coming back to what you did first,valve clearances should be (cold)0.18to 0.22 inlet--0.23 to 0.27 exhaust.also check air/vac pipes for integrity.plug gaps1.0mm to 1.1mm

[m3kidds]

i adjusted the valves to spec and also gapped the plugs.

I got a 94 Integra with the stock engine and its doing the same thing, is there a temporary solution or is it just that old

IAC valve is right behing the intake manifold/ two bolts that hold it and 2 coolant hoses.

Well for my 91 CRX Si D16A6 motor. I had to unplug the IACV (Idle Air Control Valve) while the car was running and the adjust the Idle Screw which was located on the Throttle Body.
