    Trans am start up

    Ok so my Trans am starts up like a beast when it's cold! But once it starts to warm up and I stop it and then restart it it starts up kinda sluggish and sometimes seems like very hesitantly . Is there something particular to look into, don't know if it's the plugs, not enough fuel or something like a cam shaft belt. Thanks

    Are you throwing any codes? These cars have timing chains not belts. When is the last time the fuel filter was changed?

    It sounds like the fuel filter to me. Give that a try first. No cam or timing belts in LSx engines.

    +1 on the fuel filter. Next step would be to clean the MAF and throttle body and make sure the air filter isn't packed full of dirt. If it still acts up, then measure the fuel pressure at the rail. Should be at or around 58 psi if all is well.
