Condition
Some customers may comment on an intermittent stall and/or that the Service Engine Soon light is illuminated.
Cause
This condition may be caused by the nut that retains ground G103 bottoming out before clamping the splice pack securely. This results in a poor and/or intermittent electrical connection.
Correction
1. Locate ground G103 using the illustration above. The forward transmission stud is the ground location (lower left illustration) on four cylinder engines. The rear transmission stud is the ground location (upper left illustration) on six cylinder engines.
2. In order to gain access to G103:
^ On four cylinder engines, remove the duct from the air cleaner assembly to the air intake resonator.
^ On six cylinder engines, remove the air cleaner assembly.
3. Remove the ground eyelet retaining nut.
4. Remove the ground eyelet from the stud.
5. Install a flat washer, P/N 15650963, on the stud and then reinstall the ground eyelet onto the stud.
6. Reinstall the ground eyelet retaining nut and tighten securely.
7. On four cylinder engines, reinstall the duct from the air cleaner assembly to the air intake resonator.
8. On six cylinder engines, reinstall the air cleaner assembly.
