High Rev and Running rich
When I start my car it idles reving by itself from 1,000 Rpm to 1300 up and down. Also it is running very rich and has a very strong gas smell. Any ideas of what this could be?
I have a 2000 civic Ex, with headers,cai,exhaust and upgraded ecu..

The idling problem might be due to a dirty IACV (=clean with carburetor cleaner), bubbles in the cooling system (=bleed system), or an intake air or vacuum leak (=spray carburetor cleaner around hoses/gasket to see whether engine bogs).
As for the running rich, the primary O2 sensor or its circuit could be faulty.
