2001 A4 2.8 30v p0300 ramdom engine misfire??
A4 2.8 30v Q 55k miles. Got blinking CEL and a p0300 code.I replaced the spark plugs, the spark plug wires and i am still having the same problem. The car is still running really rough and im not sure what else i can try. What are the changes of all my coil packs failing at the same time>? I dont think my car has an ICU does it? i dont get any other codes! Fuel filter? but the car is not sputtering...any advice would be greatly appreciated!
