98 Cobra
I got the check engine lite and the code is p411
What is it and how do you fix it?
Found this:
fix for Idle speed system not controlling idle properly (generally idle too high) - ISC
The idles fine and runs like new. Is there something I am overlooking?
Thanks in advanced.

Reason: ofrgot the car info
it could be a vacuum leak or the throttle valves are not fully closing.pcm senses the iac steps are too low for the engine rpms values stored in memory.
