Hi, I did a valve cover change and also cleaned the upper intake plenum and throttle body and IAC valve. I took apart the intake plenum and disassembled the vias components enough so I could clean the plastic intake plenum. I thoroughly cleaned the plenum and after it was very clean I put it all back together and also the EGR valve. After putting everything back together the car would not idle on start up and I had to use the accelerator to keep rpm high to run. Basically car would not idle and there are no codes. Being that I did not remove the IAC from the throttle body while cleaning and only soaked the bypass cavity with throttle body cleaner and after some reading on the internet I bought a new IAC valve and also took the ECM out and took the cover off and inspected the circuit board for melted or burned areas and it looked fine. I changed the IAC valve and put it back together and ran the car and car will not idle and once warm will hold various rpms after moving the throttle. I want to try a IAC reset or relearn procedure but have not found a good how to video or stepson internet specific for my car. There are none or never were codes. Car ran fine before I took everything apart and changed valve cover gaskets and disassemble all these components. I think since I meticulously put everything back together properly I might have hurt the original IAC valve with so much throttle body cleaner and so I elected to change it. I am looking for the IAC relearn steps I can do at home without a tester.
have the same problem?
