Question about GMC Cars & Trucks
I got a 1989 gmc s-15 2.5
The engine timing is supposed to be set automatically by the engine computer. If your timing is off, either the timing chain (or belt) is worn and needs to be replaced, or the crankshaft sensor housing is cracked and no longer holds the sensor in the correct position.
