1993 GMC Safari ProblemsDoor Locks Stop Working
The power door locks may stop working in one or more doors due to a failed actuator. Replacement of the failed actuator should correct this concern.
Vehicles using the enhanced vortec V6 engine may be hard to start run poorly and/or use to much fuel due to a fuel leak inside the intake manifold plenum. Commonly this is caused by a leaking fuel pressure regulator or fuel line. The fuel system will need to be pressurized with the upper intake manifold removed in order to determine the exact cause of the leak. Removing the "tuning valve" from the upper intake can allow for limited visual inspection without removing the upper intake manifold.
4.3L V6 multi-port FI only
The exhaust gas recirculation valve (EGR) may stick open causing a rough idle and the Check Engine Light to illuminate. Our technicians tell us that a piece of carbon may become stuck in the valve causing this problem. Cleaning the valve will usually correct this condition, in some rare cases the valve will need to be replaced.
