I have a 1999 Honda Civic EX, I got this car 1 month ago from a used mom and pop dealership and I been checking everything on this vehicle...
Starts up good in the morning, but lets say I go to walmart for 1 hr shopping around and then go to my car to start it up... and Boom surging idle for 10-20 secs from 1k to 1.5k rpm then settles down after that, unless I turn on the AC then my idle clams down instantly.
I cleaned IAC
THROTTLE BODY
REPLACED COOLANT AND BLEED FOR AIR
REPLACED SPARK PLUGS
REPLACED FUEL FILTER
I do have a leak on my vtec selinoid but will replace the gasket next week.
The car never stalls and almost has perfect idle after driving and stopping at a red light, just cant figure out why it is surging on warm startup, no surge if engine is hot just only when its left parked for more than 30 mins... thinking its running rich cause I can smell gas when the surge happens.
PLEASE HELP ME!
