The EPC and Malfunction Indicator light came on while driving for one second? What does that mean?
EPC and Malfunction Indicator Light on 2003 Volkswagen Jetta
Could be a MAF sensor. Bring it to autozone and have them pull the code.
You state "light came on while driving for one second" that means the light went off? did you by any chance look in the owners manual ?
It could be thortle body, pedal thortle pedal or MAF sensor
