Services Performed
- Engine Faults: P0301-00
- Cylinder 1 Misfire Detected – – Pending DTC – Warning Lamp On. P0316-00
- Misfire Detected On Startup (First 1000 Revolutions) – – Not Current DTC. Misfire history data shows faults only on #1. No hydrocarbons detected in the cooling system. Have not been able to duplicate misfire in shop or road test yet. Removed and tested the #1 ignition coil. Found good output at over 35kV, but when fully loaded the spark will arc out between the boot and the tester (where the plug would be). Carbon tracking noted on inside of boot. Inspected spark plug and noted tracking in the same spot on the plug and spark plug gap worn .003" over max gap range of .049-.053". #1 cylinder is on front bank, rear bank not accessible without intake plenum removal. Advise to replace spark plugs, install 3 new coils in rear bank (due to accessibility), and the coil boots on the front bank.
