86 iroc idle is high.

Hi guys,

When I first go out and start my car it will stay idiling at just over 1500 rpms, I know that's to high, it should be around 800 rpms....it is the 305 tpi.

What is the issue?idle set to high?

Thank you!

Re: 86 iroc idle is high.

that is a little excessive you should be around 1,100 rpm on cold startup. Start with setting your minimum idle speed and resetting the tps followed bye looking for vacuum leaks.

Exactly, how do I go about setting that?I have never messed with a tuned port engine before.

Thanks.
