i have a 99 audi, i took it to get the oil changed and now the radio doesn't work the a/c won't come on and the rpm doesn't go past 1500, and like 15 miles an hour when i have the gas pedal all the way down, then when i hold it down it will get up but jerks ALOT. i changed the battery and they did a test on all of that it's good, they tried to test the engine at 2 different mechanice but they can't get it to link u. i don't want to drive it to the nearest audi dealer, its like an hour away and i don't want to mess something up even worse than it already is....anyone have any suggestions on what the problem might be?
