I have had my A4 for about 4 months now. It's a 99 Automatic Quattro with 93,000 miles on it. When I bought the car, everything was smooth and perfect. For the first 3 months it stayed that way. Within the last month it has felt like a dog. It feels like the car has no strength left. It seems to shift weird also. When I brake, the car feels like it stumbles and just today when I was driving it, I heard a strange snapping or popping noise under the hood or near the tire. I really have no idea whats wrong. I thought it was all in my head, until I started noticing these things. It seems to operate very differently in different weather patterns and today was the first hot day around here. Has any one heard of this??? Any ideas at all????? Thanks.

 

Any ideas?

 

could be a few things.is it a 2.8?.fuel filter and tranny fluid change should be done,and air filter of course.stumbling could be rorque rod bushing(front engine mount).if timing belt is going to be done,be sure they replace the front engine mount at same time to save a lot of money,or vice versa.def. start w/fuel and air filter.
