okay i have a 2003 a4 1.8 and my epc light came on. My car ran fine for a few weeks and then this morning i was driving to school and my carsrpm got stuck and itried togive it gas and it wouldnt respond. I ended up turning into a parking lot Coasting and i say coasting because the car was moving at a snails pace but still made it up a hill to get into the parking lot but still no throttle response. After that i turned my car off and then back on and the problem was solved. Just wondering if anyone has an idea wat it might be.
