My car has been sitting for a couple months... Recharged the battery and went for some fresh gas... I noticed a surge during idle like a car with a large cam. I figured it would smooth out after driving but it didn't. I have a F.A.S.T engine management system. Any ideas what could cause this? Also, I couldn't remember if the last time I got gas, was it non-ethanol or not.

Also noticed that when I turn on the air conditioner it's more pronounced up and down idle..
The car almost wants to stall..

Without seeing data from the fast, its a shot in the dark.

Hook up to the laptop and check the map signal and ve table. You may just need to adjust fuel in few cells.
 
Thanks for the reply guys! I will check those suggestions and report back!
