Dis-connect the cam sensor while the car is running and try it again.

Scanmaster readings?

IT is a long shot.... but mine did the exact same thing when my battery cable was too close to the pass header near the starter... and when I would romp on it.... it would temporarily short out to the header.... once it stumbled... it would unshort (cause the engine would rock over toward the drivers side.....). Once I taped this wire up good......and zip tied it out of the way.... no more problems....

What code are you getting?

well i havent scan it yet again for codes since the first time i got codes.I know the first time they were,o2 sensor lean,maf error(?) and tps open? on the snap on diagnostic tool.My scan master is defective(i need a new one ) no numbers appear on the screen. Since then ,i have replaced the maf sensor,the tps sensor and the damn thing still hesistates. i will direct scan the sucker today at conley's performance to see what the hell is the problem. yet again,thanks again for the inputs

Look at the wastegate solenoid. They can fail 2 ways: Lack of boost, & over boost. Yours sounds like so much boost it cuts out. Also, clean your fuel injectors, & change your fuel filter.

ima look into the cleaning of my 50 pounders,and my swap of a new fuel filter.I also think something is wrong with the wastegate solenoid,but i adjusted the new tps sensor.The engine engine went off,and the car seem to pull harder(running good finally after a month) thanks guys,,,,,very helpful indeed...thanks again
