My passat is misfiring and I read the codes, it is showing no. 2 and 4 cylinders misfiring, codes po300,302,304 and fuel injection circuit open codes p1237, 1238, 1239,1240 I moved some fuel injectors around and also some sparkplug coils and it is still doing the same thing. Does anyone have any suggestions to fixing this problem. Please let me know.

well if i know the coil packs for vw suck i have had the prob but the i believ on your car there is part on top of your air box i cant quite remember what its called but those are the biggest problem on those cars, i know on mine i found a broken wire in the harness, and the first time mine started to mis was the number 2 and 4 coil pack was bad.
