A little history, gf has a 2002 tt 1.8, the engine light is on throwing code p0340 camshaft position sensor a circuit (bank 1 or single sensor) runs decent but once it a while it'll stutter. Replace the sensor no change. The timing belt was changed before we bought it(last June) so i don't think the timing belt was off because the light hasn't been on that long. They did replace the head gasket and water pump recently could they have somehow screwed up the timing then? first turbo and I'm honestly not familiar with Audi's so could this be the issue or could the new cam sensor be faulty? Oh and i believe there is a cracked ignition coil i believe because when it's wet out the car stumbles a lot and doesn't run right, but only when it's wet out. Already ordered new ignition coils. Thanks for any help and sorry if these are stupid questions but i really don't want to screw this up, she'd kill me, lol.
