- 10 Point Vehicle Inspection Check under hood fluids, drive belt, operation of exterior lamps and condition of tires
- Performed GDI upper intake service
- Removed plugs and installed new ones. Cleared codes and road tested. Cones did not return
- Scanned ECM and found 2 stored history codes. P0303 – Cyl#3 misfire and P0269 – Cyl#3 contribution/balace. Both are history codes and not currently active. Removed and inspected a couple of spark plugs for wear. Engine has iridium plugs. Maintenance schedule says that spark plugs are due at 80,000 miles. Recommend tune-up service with BG GDI fuel induction service. Problem could also be with #3 ignition coil, but it is currently working without failure. Recommend moving cyl#3 coil to one of the front bank cylinders while replacing spark plugs, since #3 requires removal of the intake to access. This way if misfire comes back due to a bad coil after tune-up service, that coil will be easily accessible.
