I did oil filter housing replacement work on this car so i R&R the intake manifold, used new gasket, new throttle body gasket as well but car records intake system air leak. I also have this beetle which misfires only in cylinder #4. I have checked vacuum leaks, non found but the pcv diaphragm looked so old and tiny holes so i replaced it but still. I removed and rechecked intake manifold again but all gaskets look fine. No carbon deposit found on valves! No cracks found in intake air hose. I did carry out smoke test but nothing significant found. Also the misfire in cylinder 4 occurs only when at vehicle station and idling mode with gear in Park but no misfire occurs while driving. I replaced spark plug and coil for Cyl #4 but no change. MVB 032 shows 0.0% idle self adaption but 10.2% Lambda self partial adaptation.
My next move will be to check compression and test the #4 injector, but strangely car still accelerates well during the 6 mile test drive. Any leads will be appreciated!
