Can't Get Rid of Misfire
To start, my audi had several misfire issues and codes. Since then most of the codes have been resolved except:
3 Faults Found:
16684 - Random/Multiple Cylinder Misfire Detected
P0300 - 008 - Implausible Signal - Intermittent
16688 - Cylinder 4: Misfire Detected
P0304 - 008 - Implausible Signal - Intermittent
16686 - Cylinder 2: Misfire Detected
P0302 - 008 - Implausible Signal - Intermittent
I have replaced all 4 coil harnesses. New Spark Plugs. New check valve. New suction jet pump.
After seeing the two cylinders misfire I assumed the problem was bad coils. I rearranged the coils, cleared the codes and the same three codes appeared again. Any ideas??
