    car wouldn't start so i replaced the fuel pump and put more fuel in it and it runs good at idle. when i would hammer on it in neutral as soon as boost tried to build it would start cutting out and falling on its face.. so i found a vacuum hose disconnected put it back and now it only cuts out under load when the boost starts to build please help.. changed fuel filter right before the old fuel pump went out

    Well, if it is only doing it UNDER LOAD, I would suggest checking the CAT. BUT if it is only doing it under BOOST AND LOAD, it might be a different problem.

    its a 99 gtp and the cat is gone.. could the fuel filter be plugged up again already?? and also are there any fuses or sensors or anything.. I'm so lost on this I'm a diesel guy lol

    lol, neither of those would cause issues.

    Check your plugs/wires/coils.

    Really.... It is ok to have a bad Cam sensor and/or a bad ICM?

    Like I said it was doing it in neutral way before limiter and I got it fixed now it just goes to the limiter.. However under load it runs like total crap that's what I'm trying to figure out
