Today, the car suddenly started running rough and makes a tapping noise. Accelerating seems to smooth out the roughness, but not the noise. Noise seems to be coming from under the intake right about in the middle. Engine scan revealed a "Cylinder 6 Misfire" and O2 sensor.
- Checked #6 plug, it was clean. Regapped to.060 and reinstalled.
- Removed coil pack and inspected. No cracks, produces spark
- Plug wires are new, power does go to the plug
- Good fuel pressure
- Not using (burning) coolant, no apparent air leaks
Now I'm stumped!
have the same problem?
