Idle surge :(!!!

:glasses4::glasses4:My aveo runs great no problems what so ever, just surges on idle. I have cleaned throttle body, new idle control valve, new computer, removed intake for a good look at any vaccum hoses or elboes that may have split, and i cannot find anything. please help. The only thing i notice is the power brakes dont seem as easy as they should be, but they do work bc i pluggd off the booster in the case that it was leaking vaccum inside, and they were even harder. And it didnt help the idle

From my experience, idle surge is almost always a vacuum leak somewhere or a sticky IAC valve.

I'm sorry to hear you're having these issues but I'm unable to diagnose. If you would like to private message me the last 8-digits of your VIN, I would be glad to research further to see if there are any special coverages or bulletins related to the issues you're having.

Best regards,

my 2007 aveo5 LT hatchback tries to surge when in park and at complete stops but I have no idea why. Any help would be appreciated TY
