hey guys. have a 97 ek d16y7 (119k miles.). 2 days ago i decided to clean my IAC Valve. also removed the TB to clean it. while i was at it, i decided to install a new pcv valve (easier acces to it). after installing the new pcv valve and cleaning the iac and tb, i installed everything back including a new tb gasket. didnt start the car up right away. today when i started it, it was idling high then came down a bit and now the idle is crazy. it drops and goes up again continuously. already reset the pcm. anybody with the same past experience? any ideas what the problem is? oh and its not throwing the CEL light.
i dont get it. you clean one part and it turns out to be worst.
