1996 GMC 2500 Pickup Problems

Check Engine Light With Code P1870

Vehicles equipped whit a 4 speed automatic transmission may develop a harsh 1-2 shift and/or illumination of the Check Engine Light with code P1870 stored. This can be caused by wear of the bore for the TCC isolator and regulator valves in the valve body. This condition does not commonly occur until the transmission reaches normal operating temperature. If the valve body is worn, replacement will be necessary to correct this concern.

Check Engine Light and Misfire Due to Stuck Fuel Injectors

One or more fuel injectors may become stuck closed causing an engine misfire  and the Check Engine Light to illuminate. Our technicians tell us that this problem can be caused by some fuel additives. There are special procedures which may be able to restore the affected injector. If this fails the affected injector must be replaced.

Deposit Buildup on Throttle Body May Cause Low Engine Idle

The engine idle may be lower than normal due to deposits built up on the throttle body, which can restrict air flow at idle. To low of an engine idle can result in a stalling condition. Performing a throttle body service will generally correct this concern.
