Known Problems

A condition may develop where the fuel gauge reads empty with too much fuel still in the fuel tank. Our technicians tell us that installing a new wire harness that provides a common ground for the fuel gauge and sending should correct this issue.

The engine may develop a rattling or lifter type noise from the timing cover area. It may also exhibit a more general valve train noise. Our technicians tell us that a revised timing chain, sprockets, and tensioner are available which may correct this concern.

The engine may develop a lack of power or stalling condition due to low fuel pressure. Our technicians tell us that this can be due to contaminates passing through the fuel pick-up screen resulting in fuel pump failure. If fuel pump failure occurs it is recommend to replace the entire fuel pump module as it includes both the primary and secondary fuel pump filters.

An internal oil leak may develop from the intake manifold plenum gasket. The symptoms could include engine spark knock on acceleration and increased oil consumption. Our technicians tell us that replacing the plenum gasket should correct this issue.

The powertrain control module (PCM) may fail resulting in a lack of AC cooling. The lack of cooling could be caused by evaporator freeze-up due to the AC compressor staying on continuously or conversely, not coming on at all. Proper diagnoses of the PCM should be performed before replacing it for this concern.

The following cooling system components are prone to leaks: Thermostat housing gasket, water pump, heater tube o-ring at water pump housing, intake manifold gasket, and timing cover gasket. These are generally external, not internal coolant leaks so intermix with the engine oil in uncommon.

Under light load, at approximately 2000rpm the engine could exhibit surging, bucking, or intermittent misfires. Our technicians tell us this could be caused by a mis-indexed distributor.

An intermittent fault with the electrical connection at the crankshaft position sensor may result in poor engine performance and/or a no start condition.

Erratic idle conditions which can include engine stalling may occur in warm to hot weather. Our technicians tell us that a new idle air control valve is available to correct these concerns.

The fuse may blow repeatedly for the HVAC blower motor or the motor may stop working all together. Our technicians tell us that can often be repaired by replacing the blower motor switch with a revised switch and installing a wiring harness with a relay assembly.

The blower motor may operate erratically and the blower switch operation has a sticky or mushy feeling, the detents almost non existent. Our technicians tell us that the blower switch should be removed and inspected for overheating. This is common if the blower motor is frequently operated on high speed as the current flow through the switch tends to melt internal the components. Also carefully inspect all of the switch connector terminals for discoloration due to overheating and replace as required. A poor electrical contact at the connector will also cause the switch to overheat.

The AC/heater (HVAC) system may unexpectedly switch to the defrost mode when accelerating. This system is operated by engine vacuum and should be inspected for any vacuum leaks if this problem develops.  There is also a revised vacuum check valve available to address this concern.

The engine my develop and buck, surge, or noise due to a worn distributor drive gear. If the distributor shaft has excessive rotational free play the distributor drive gear and bushing should be replaced.

The transmission may exhibit a delayed engagement after the vehicle has been parked for an extended period. This condition can be caused by transmission fluid draining back into the transmission from the torque converter. There is a drainback relief valve available which should be installed in the transmission oil cooler pressure line to correct this issue.

The manual transmission may become stuck in or blocked out of reverse or 5th gear. Our technicians tell us the repair involves replacing the transmission overdrive rail, lug shift fork, and synchronizer assembly with revised parts.
