Hey guys,
I have a friend whose RT/TT idles rough and he can't find why that is happening. When idling, the car is shaking and so on. When he hits the gas and goes over 2000 RPM, the issue goes away... He has taken the car to several different shops where they have diagnosed it, but could not find anything wrong with it. His problem is that he lives in Eastern Europe and there are no mechanics that know our cars well enough there... He has replaced the ECU with a rebuilt one that was tested and worked good, but that did not fix the problem. The compression is great and the diagnostics show that everything else is fine. Could it be his air filter (MAS?) sensor? Dirty throttle body? What else could be causing that? Any input is appreciated. Thanks!
