WHAT UP! AGAIN I GOT A PROBLEM WITH MY 86 IROC IT WONT IDLE ON ITS OWN WHEN ITS COLD. WHEN IT WARMS UP IT WILL IDLE ALITTLE ROUGH BUT IT WONT SHUT OFF GAS FUMES ARE STILL A LITTLE STRONG. I WAS THINKING OF CHANGING OUT MY I.A.C. BUT I RATHER GET ADVICE FROM YOU ALL..THANKS IN ADVANCE

 

That's what I would recommend. We had a problem with ours not wanting to start at all, and after we replaced the IAC it works great.

 

well today i changed out my broken oil pressure sensor and the car idles nicely.thanks for the reply halo nick ill checked that if it acts up again...

 

I didn't even think about sensors. Probably good to get it replaced anyway.
