Car is a 99 a4 drove fine from what I could tell the night before, got up this morning and car runs rough at low idle at first then smooths out, runs fine if rpms kept above 2000 but misses and sputters bad if in over drive and shifts up to where rpms drop to range of 1400 to 2000, also i think the miss is coming from just right side of exhaust as left side does not seem to sputter. any help would be appreciated thanks

Have you checked for DIC codes? That would be a good starting point.

How about filling out your sig. Have you ever changed the plugs and wires? How many miles on the vehicle?

Considering the car is almost 10 years old, and the plugs are only good for 5 years , don't you think that's a good place to start? Either way, it's time for the plugs and wires to be changed.
