The accumulation of moisture at major connectors and control units can cause various ABS/PDAS faults due to corrosion.

Check Engine Light illumination and performance issues can be caused by oxygen sensor faults.

Cam tensioner/cam timing issues can cause the Check Engine Light to illuminate.

The engine may have a misfire, hesitation, and/or run roughly – notably after a service and/or ignition wire replacement. If after recent ignition wire replacement, the cause can be misrouted ignition wires. The wires from the distributor to the valve cover must be routed correctly to avoid interference and induction crossfire. Verify all clips are used to secure and separate ignition wires.

An engine misfire may develop from one or more cylinders resulting in a loss of power and illumination of the Check Engine Light. Our technicians tell us that ignition coil failure is a common cause for this concern. On high mileage vehicles it may be wise to consider replacing all of the ignition coils if one fails to try and avoid future misfire issues on another cylinder.

The spark plugs may become dislodged from the cylinder heads. A loud popping noise can be heard and a subsequent misfire experienced. The threads on the spark plug ports in the cylinder head(s) can become stripped or missing when the spark plug is dislodged. The threads in cylinder heads may be replaced using “Lock-N-Stitch” aluminum inserts. Our technicians tell us thread replacement is performed when the vehicle is out of base warranty. Vehicles under base warranty receive a new cylinder head.

The Check Engine Light may illuminate, the engine may run rough and have misfires on acceleration. Commonly the ignition coils and/or the ignition coil boots are the cause of this problem. The rubber boot that insulates the coil to the spark plug can dry and crack allowing arcing. Inspect the coils and boots, and replace them as needed. Our technicians also recommend replacing the coil boots any time the spark plugs are replaced.

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 direct ignition cassette can fail causing the engine to die while driving, and/or it will crank but start. Diagnosis may also discover trouble codes for random misfires.

Misfires under load (acceleration) can be caused by leaky spark plug boots. When a spark plug boot leaks, it allows the spark to arc, or jump, to the cylinder head. New spark plug wires will be needed.

Vehicles with a V6 engine may develop an engine misfire under load (acceleration). This can be caused by a valve cover gasket leaking oil into a spark plug well, shorting the spark plug to the cylinder head. To repair this concern, the valve cover needs to be resealed and the spark plugs and wires should be replaced.

Misfires under load (acceleration) can be caused by spark plug wires arcing to the cylinder head in the spark plug wells. Water in the spark plug wells can also cause the same problem so careful diagnosis is needed.

If the Check Engine Light comes on, and diagnosis finds a trouble code, or codes, for misfires, it might be caused by insufficient valve clearance for the affected cylinder. The valve clearances should be inspected and adjusted where needed.

Misfires under load (acceleration) can be caused by leaky spark plug boots. When a spark plug boot leaks, it allows the spark to arc, or jump, to the cylinder head. New spark plug wires will be needed.

A loose or corroded ground terminal on the driver's side of the cylinder head can cause a rough idle, misfires, and there may be trouble codes. Restore the ground to the cylinder head.

Misfires under load (acceleration) can be caused by leaky spark plug boots. When a spark plug boot leaks, it allows the spark to arc, or jump, to the cylinder head. If evidence of arcing can be seen on the inside of the spark plug boot, new spark plug wires will be needed.

A rattle from the rear of the vehicle may indicate that the rear shock absorbers are defective. Updated shocks are available; however, careful inspection of all suspension components should be performed before any parts are replaced.
