B8 Audi a4 misfire issues

Been fighting with misfires for a few months and found them to be fuel related. In this video I fixed the misfire in cylinder 4 by replacing the injector and ended up with a cylinder 3 misfire. After some testing after making this video I think I found the source of the issue which is oil in the air intake system which I will correct in the next video. #audi #misfire #volkswagen #carrepair #racecar #fuelinjectors #fuelissues #oilissues #turbo
