i have a 98 civic cx sir swap. car ran fine till i put a skunk2 mani on know it idles high till it warms up then the idle bounces. i pulled mani off and checked for vac lead and reinstalled new gasket. same deal what else could it be. iac is torqued down new gasket on it. throttle body new gasket. pretty much everything new gaskets. that is why i don,t understand. Please help. thanks

 

Is the CEL ON?

Spray some carburetor cleaner around intake gaskets and vacuum hose connections (brake booster, cruise control, PCV, etc.). Any change in idle speed would indicate a leak.

 

its probably your idle air control valve

 

thanks. i have no cel and i have tried carb cleaner and it is around the third injector it bogs down when i spray it. my fuel rail isolators are broke so i wonder if my injectors are not seated all the way. i am putting new ones in today maybe that will work. if not it may be iacv. i hope not it is like $211.
