i tried this on another topic but it went unanswered and was the opposite throuble aswell. My problem is absolutely killing me in the mornings.

i hate cold mornings as so does my car, its having starting troubles and the cold only makes it worse. When starting my car on a cold start after its been sitting aorund for a few hours (or all night) the idle is real high (2500-3000rpm) then it pulses/fluctates each second up and down from around 1000 back to 3000. Once i let it do this for a while the high end of the idle gets lower and lower and eventually the idle is just fine, down to a normal 500-750ish. Only works right when its wamred up

The colder the engine, the harder it is to get the car to start, which is harder to keep it alive cause it fluctates so bad on freezing mornings it shuts off.

A buddy of mine told me to take apart the sall peice behind the throttle body with the plug and 2 hoses (in my 91 crx hf) did it but didnt change anything. Hes unavailable and i sure as hell dont want to shop this one. Winter is upon me help!

 

What motor? Sounds like a problem with an FITV (if you have one ).
