The trouble shooting section in the Chilton/Haynes repair manual that covers your truck will lead you to most likely through least likely reasons for this stumble while running. I just checked my own repair manual (1992 GMC Sonoma). Most likely problem is in HEI system. I would suggest a full tune-up if one hasn't been done in memory, if at all. (My father-in-law bought a couple used cars that had misfire codes. Pulled the plugs and found they had NEVER been replaced in over 100,000 miles.) Replace plugs, wires, distributor cap etc. Be sure the plugs are gapped correctly, etc. Best of luck with your GMC. The bad news about these newer GMCs. I had to get a special wobble-socket and take the front tires off of my truck to change the front 2 spark plugs. You have to go through this little hatch type opening in the inner fender well to access them. What a bummer.

Car runs perfect then starts missing real bad then stalls


Not unusual for fuel pumps to begin to fail once they are heated up from running. First thing in the morning pump is cool, then as you drive, it heats up and begins to lose pressure. After sitting a 1/2hr-1hr, it may start again and run fine for a short time and start to act up again. Had similar problem and found good fuel pressure when tank and pump cool, but lost pressure once vehicle driven a distance and pump heated up. The hotter the weather, the shorter the distance I could drive. If you can somehow set it up to have fuel pressure checked when it starts to act up, that would certainly help confirm if fuel pressure is the culprit.

Try spraying a fine mist of air induction cleaner in the throttlebody while the engine is running. If it stops missing you have an injector that is not working.

How about the pick up coil in the distributor? A trick we used to use back in the day was to tap the distributor housing with a hammer, key word tap. If the engine missed or stalled than the pick-up coil was replaced.
