2002 GMC Sonoma ProblemsDistributor Shaft O-Ring Seal May Leak Oil
An engine oil leak may develop from the distributor shaft o-ring seal.
The distributor may develop internal faults. This can cause a rough running engine or stalling condition and the Check Engine Light may or may not illuminate. The distributor should be overhauled or replaced to correct this concern.
It is common for the fuel level sensor in the fuel tank read the fuel level incorrectly. The sensor must be replaced to correct the condition. Our technicians recommend having the complete fuel pump module replaced on high mileage vehicles.
