I got 1988 honda accord 5 speed 2.0 motor fuel injected its 231,000 on it. It runs good but when it is cold out like around 40 degress or below when u go out to start it when the motor is cold it will idle at high rpms first for like minute or so then i will start fluxuating back in forth from 1 to 2 rpms for like 10 minutes or so then after that 10minutes or so it will idle right. But when it 45 degress and hotter it wont do that it wont idle up and down only when its cold.
Ive change the plugs and wires air filter i have tried a fast idle control valve. Any one know what it could be or maybe someone has had the same problem let me know please.

 

did u try www.3geez.com?
