I was drivin home from work in traffic an my car stalled out. So I started it back up n it turned over. My epc light came on while drivin after the light came on my car stalled out on the highway it didn't want to turn over so I did a rolling clutch start. It turned on with epc light on everytime I hit the gas it struggles to gain speed. N if I stop it wants to shut down. My friends told me it's cause my system in my car n I need a capaciter. But it was running fine for the 2 years with no problems. I have a 2005 a4 Audi 1.8t quattro 6 speed I just worried if I blew the main computer or it something smaller than that. N the car is stock no upgrades. Need help anyone
