    2004 Tahoe 5.3 wont stay running unless im on the throttle.
    Been sitting for a bit with dead battery/bad connection; fired right up tho.
    Run fine moving forward, stopped, then died.
    Started right up, put in reverse, died as soon as it stopped.
    Started up again fine multiple times, could rev the piss out of it with no issue.
    As soon as I let it idle it would hover low and die.

    No SES or Security.

    My first thought.
    It was a spark plug lead.
    I double checked them.
    Drove the piss out of it then starting hearing the arking noise.
    Now I know to pull them and reseat

    being it sat for a while. take a good look for a mouse nest, they love the air filter box. then the nest clogs the air intake.

    they also tend to chew wires too. so be on the look out for damaged wires.
