1992 GMC Sonoma Problems

ABS Light Due to Brake System Control Unit Failure

The Anti-lock brake system (ABS) control unit may fail internally causing the ABS warning light to illuminate.

Engine Running Rich Due to Fuel Leak Inside Intake Manifold

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.

Distributor Shaft O-Ring Seal May Leak Oil

An engine oil leak may develop from the distributor shaft o-ring seal.

1992 GMC Sonoma Reviews

Great truck that will get you anywhere, mine is a Vortec 4.3L V6 and gets 22-24miles to a Gal. Nuts! It can take me on 4 hours trips or across the street. Drives in water and snow ok. Get the 4x4 though the RWD is not very good in Snow/Water.
