I have a 2003 Audi a4 3.0L with 107k miles. When I first turn my
Car on in the morning and begin to accelerate, it jerks and jerks when stopping. But when it warms up to regular temperature, there is no issue. Maybe a vacuum leak? Any advice? Thanks!

 

I have the same issue on a 2005 A4 with 68K miles on. Can any pros help plz

 

I've figured it out I think. I put a k and n drop in filter and the oil fouled up my mass air flow sensor. I put a dry filter and cleaned my maf and it helped a little. But I think it's too fouled and I need to replace the maf because its still doing some jerking at shifting times and stopping.

 

PLEASE HELP!!!!

Ive replaced the maf, ECT, and took it to a shop where they think its internal transmission but i disagree. Im going to change the fuel pump relay and the fuel filter to see if it changes at all. Im also going to add some BG transmission additive to see if it helps. I guess if none of that works maybe fuel pump, coils, plugs...? any suggestions!
