I have a 1999 eclipse gs with an aem cool air intake, greddy headers, airmass catback exhaust, nology spark plug wires, nology spark plugs, stage 2 chip. The problem is that at idle it fluctuates between 800 and 900 rpms. It does not do this all the time but I was wondering where I should start look for a cause??

Thanks

Yep stock idle is 800-900 rpm's, your fine, but a little paranoid
