Subject: INTERMITTENT CHECK ENGINE LIGHT, ENGINE STUMBLE, OR NO-START

1985 FIERO WITH V6 ENGINES
CONDITION:

A wire harness rub-through may cause an intermittent check engine light, engine stumble, no-starts, or an intermittent speedometer.

CAUSE:

The engine wire harness located over the right hand axle shaft may contact the shaft or axle boot due to excessive slack in the engine wire harness.

CORRECTION:

1. Remove threaded fasteners that hold wire loom harness over axle shaft.

2. Reroute harness by alternator to remove excessive slack (auto trans).

3. For manual trans - eliminate harness droop between fastener clips by having extra length fed toward P.M. generator.

4. Reinstall fasteners.
