    A good place to start with these trucks is a tune up. Plugs, wires, cap & rotor, fuel and air filters. Only use AC Delco plugs, cap & rotor. Napa PREMIUM wires are OK, and quite a bit cheaper than AC wires.

    Some good reading here.

    You can do some searching also. A wealth of info on this site.

    What are your plugs gapped to? Probably should be .035 for TBI. Make sure they are genuine AC Delco.

    I would start by changing them to AC. I had a tremendous difference when I went to AC, and many others on this site agree they are the best for our Chevy trucks.
