Sounds like a bad TPS but clear the coades and see what returns

 

99 A6 Avant - 2.85V engine - Can i just get the TPS sensor? called ECS tuning, and they said I have to get the whole throttle body? http://www.ecstuning.com/stage/edpd/...ategory=Engine

Also, is their another source for Audi parts you know of??

 

Call Chris semple at Force Five in Concord NH - 603-223-6700 he sells new and used Audi stuff. he dosen't like to diagnose but he is willing to give you buying options...

 

If you want a good selection id try a parts locator. One place that can find you a good short or long block for a Audi A4 used dodge engine is TEXAS Junkyards, Junk Yards in TEXAS TX salvage recycler. They have a link somehow to multiples of thousands of recycling centers and will locate the best one for you.
