    Unhappy 2001 Silverado 1500 with issue

    2001 Chevy Silverado 1500 V6

    The problem is it has a mystery missfire that is sporadic or not all sometimes.

    New disty cap and rotor, new wires and new plugs.
    New fuel filter.

    Has approximation of 179,000 miles

    No error code given for this problem.

    Only error code is showing up is for the fuel tank pressure, it comes and goes.

    I've heard the problem could be the spider fuel injection assembly.

    Welcome to the club, Bryan. What brand of spark plugs did you install? Most people on this site have found that GM's seem to like A/C Delco plugs. Some other plugs have caused a misfire.

    I used NGK V-powers, but it was doing it prior to the plug swap so that's not the issue, I figure It's the fuel injector assembly and i'll have to upgrade to the better vortec system
