The car is all stock, I just got it running a few days ago from a MAJOR electrical malfunction. Im not sure im hitting the fuel cut if the car is all stock...maybe if I was running more boost. I did try adjusting the TPS(throttle sensor). If this was even slightly off would it cause this problem?

From what I gather adjusting the TPS is a major no, no. Our car pretty much adjusts everything for us. As for the fuel cut, it is possible to hit it with most likely a malfunctioning boost soleniod. Mine used to hit it all the time. A MBC and FCD would most likely remedy the situation.

it almost seems like I am not getting enough fuel, I am going to check the pressue at the fuel filter and at the regulator to see where the problem may be. would I need aMBC if I am running stock boost? BTW how much is stock boost.
