Im a chevy guy but i also know a bit about gmc and the one thing i can tell you is that both have problems with the distributer having to much play in it to check it you just pull off the cap and leave the rotor on and see if you cna move the shaft to either side replace it if it has play also check to make sure you have the gap in the plugs set right if its a sencer problem your check engine light will come on.
