I got the following problem.
When I start the car the idle is normal, but when it's completely warmed up, the idle is jumping between 1000-1200 rpm. Sometimes 10 times and than it runs normal again. I cleaned the iacv, but it wouldn't help. Should I replace it or could something else cause this problem? Maybe a bad Lambdasensor or vacuum leak? There are no codes.

It happened after I swapped a itr intake manifold, itr iacv and skunk2 tb on a b16a.

thanks!

No it's not tuned yet, it will be tuned next week when I got my plx wideband.
