EPC Light Is On, On My 2001 VW Jetta

Hi, Tom & Ray, I love Your Show. I listen To every Saturday Morning In St. Louis. The EPC Light Came On On My 01 Jetta all of the sudden, the car runs rough and wont allow me to accelerate. I cant afford to go to the Dealer. Can Please Tell what is the cheapest way to fix this problem. Thank You

The EPC is the Electronic Pedal Control. It is the gas pedal assembly which sends a signal to the engine throttle body and tells it, by electrical signal, the position of the gas pedal.
You need to insure that the engine is in the best of tune (air filter, spark plugs, clean MAF, and clean throttle body bore and throttle plate).
