Known Problems

Vacuum hose failure is common due to engine heat and time.  Vacuum hoses are made of plastic.

Poor engine grounds could cause the engine not to start, intermittent Check Engine Light illumination, and computer failure.

An EGR pintle position error is common and will cause the Check Engine Light to illuminate.

Tubes for the EGR system (exhaust gas recirculation) can break, causing an exhaust leak and noise under the hood.

For the 2.3L 4 Cylinder and 5.0L V8 engine, the electrical ignition switch poses a fire hazard. An updated switch is available.

The battery light may illuminate on the instrument panel because the alternator wire harness connector is damaged. A new connector kit is available and should be installed to correct this concern.

The front brakes may stick, bind, or grab. This can happen when the front brake caliper pins become corroded. Cleaning or replacing the caliper pins will be necessary to correct this problem.

Valve cover gasket failure is common, causing oil to leak onto the exhaust manifolds.

Valve cover gasket failure is common causing oil to leak onto the exhaust manifolds.

Rough idling is often caused by ignition wires that are routed wrong or installed with damaged tips.

The upper intake manifold gasket may fail, causing an engine vacuum leak and a high idle condition. A damaged intake gasket should be replaced.

If a noise from the rear end is heard when going around turns or after driving at highway speed for an extended period, this could be caused by a failing deferential clutch kit. An updated differential clutch kit available.

If there is a vibration or noise at highway speed, it could be from the front driveshaft and may require replacement of the double cardan joint. A double cardan joint is a type of driveshaft joint that uses two universal joints.

Failure is very common in the ignition module, causing intermittent stalling or a "No start" condition.
Rough or unstable idling could be caused by the idle control valve and throttle plate being plugged with carbon.
