Ignition wire failures can cause a rough idle or intermittent engine misfire and there might not be a Check Engine light.

Ignition wire failures can cause a rough idle or intermittent engine misfire and there might not be a Check Engine light.

A small leak from loose charcoal in the charcoal canister (part of the Evaporative Emissions System) may cause Check Engine Light illumination.

A Check Engine Light may illuminate indicating a "Cylinder #3 Misfire." This normally occurs in hot weather after the vehicle has been driven, parked for ten to twenty minutes, and then restarted. Heat from the exhaust vaporizes fuel inside the #3 fuel injector and causes the misfire. Installing an insulator sleeve normally lowers the temperature enough so the fuel will not vaporize.

If the downstream (rear) oxygen sensor wiring harness contacts the propeller (drive) shaft, it can damage the oxygen sensor and the wiring harness for the sensor, and/or cause Check Engine Light illumination. The wiring harness should be repaired and secured away from propeller shaft.

A Check Engine Light may illuminate indicating a "Cylinder #3 Misfire." This normally occurs in hot weather after the vehicle has been driven, parked for ten to twenty minutes, and then restarted. Heat from the exhaust vaporizes fuel inside the #3 fuel injector and causes the misfire. Installing an insulator sleeve normally lowers the temperature enough so the fuel will not vaporize.

An engine misfire at idle (rough idle), accompanied by illumination or flashing of the Check Engine Light, could indicate a problem with one or more of the intake valves. Revised intake valves & valve locks are available to address this concern.

When normal alignment practices do not bring components into the alignment specifications, offset upper ball joints are available.

Offset upper ball joints are available for when normal alignment practices do not bring components into the alignment specifications.

An abnormal noise may develop from the HVAC blower motor as a result of debris ingestion. After any debris is removed, an air baffle screen can be installed on the inlet opening under the cowl grill to try and prevent a re-occurrence of the problem.

A ringing sound may be noted from the driveshaft when shifting from drive to reverse and reverse to drive. The repair may involve replacing the automatic transmission output flange and applying "Stud N Bearing Mount Adhesive" to the transmission output shaft flange splines.

If the transmission delays initial gear engagement after being parked overnight or longer, it may be due to a suspect transmission cooler return filter. If the transmission was recently serviced and the part number for the cooler return filter contains an "AB" suffix at the end, a new filter should be installed.
