Hey new to here and was wondering if any one has ran into this problem any info helps. I drive a 1997 Mitsubishi Eclipse GS-T 5 speed and it starts fine but then will idle rough and low for maybe 3-5 minutes after that the idle will return to where it's supposed to be at and it drives and boosts fine. This only happens when it starts even when the engine is still warm every time I start it the idle is low for those few minutes then goes back to normal I don't know what to check any information helps and Id appreciate the help thanks.
 
Do you have a wideband? If so, what do your A/F ratios look like? Also, be sure to fill out your DSM profile so we know what kind of mods, if any, you have done to your car.

Have you checked the fiav on the throttle body? If you just recently purchased the car the previous owner may have put a fiav block off our bypass plate in.
