Hi i have 94 sonoma 2 wh drive 4 cyln.just did tune up plugs wire pcv valve.engine has a studder or skip under acceleration and some losse of power when this happens.but doesnt happen all the time.spark plugs color was white upon removel.notor running lean can ui help
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.
