Illumination of the Check Engine Light can be caused by a loose or worn gas cap.
The distributor may develop internal faults. This can cause a rough running engine or stalling condition, the Check Engine Light may or may not illuminate. Our technicians tell us that the distributor should be overhauled or replaced to correct this concern.
The spark plugs should be replaced every 100,000 miles. Our technicians recommend replacing the spark plug wires also at this time.

2003 GMC Safari RecallsBall Joints May Separate Due to Premature Wear
An interference fit between the lower ball joint rubber boot and the steering knuckle may cause the rubber boot to be cut. This would allow entry of water, dirt, salt, or other contaminants, possibly leading to premature wear. Failure from premature wear could lead to separation of the steering knuckle and lower control arm, which would cause the vehicle to drop at the affected corner. Vehicle handling and braking could be compromised, increasing the risk of a crash. Dealers will replace the steering knuckles. The recall began April 8, 2004. The GM recall number is 03044.
