I discovered that the wiring leading to the air flow meter has been cut and re-wired however, the re-wiring was wrong. The wiring was readjusted and the air flow meter began working again.

CommentNo power 1.8T

The car has no power, sometimes it runs great and sometimes it doesn't and sometimes it starts to run really well up to over 4000rpm and it seems to jerk... what's new: vacuum hoses, maf sensor, turbo, fuel pressure regulator, n75, lambda before the catalytic converter, fuel filter, spark plugs... I've been dealing with this for a year and I can't figure anything out
