I have a 99 gsr and just recently my integra has started to idle really funny. Its bouncing between 2k rpm and 1k rpm. I've cleaned my IACV but that didn't fix the problem. The car drives fine its only the idle thats the problem. Any idea what the problem is?

 

have you checked for any vacuum leaks?

 

Dude pop off your throttle body and turn it upside down and see if that white piece came loose if it did just tighten up again happened to me i got GS-R too with b20v now it idles at a cool 800rpms

 

Could have ruined the iacv by cleaning it, cleaning it doesn't always work sometimes it's just not fixable.

 

are you talking about a FICV?? I guess I'll check for vac leaks and replace the IACV if there are no leaks.
