Fluctuating idle

[Drummerboy]

When I start it up, it revs between normal (950rpm or so) to around 2K. then drops back and revs again. Almost like a consistant bounce, if that makes since.

I have an AEM wideband, and possibly an exhaust leak from scrubbing speed bumps. A friend said "it" was having a hard time figuring out the Intake air Temp, but i personally dont know. any ideas?

Reps for a fix.:goodjob:

or vac leak, or way too rich, or a f#cked up iat that's stuck below 0*...none of which will necessarily throw a code.
