Hello everyone...I have a question! I have a 1994 mustang gt that has some stuff done to it like different heads, cam, msd ignition, and a venom box on it. When im driving down the road and holding the peddle in one position it starts jerking like is not getting enough fuel or to much fuel. I have trying adjusting the fuel pressure all different ways from 20 to 60 psi and the timing as well. Checked each plug and wire too. It will idle but the idle is off an inconsistent as well. Im wondering if the pump isnt going out on me because I have to turn the key on and off about 4 or 5 times for the pressure on the guage to get high enough for it to start easy but when its running the pressure stays steady. It has a new fuel pump and filter but I wonder if the pump isnt delivering right. When I stomp on the gas it does fine only when the peddle is in one possition...Also at idle it runs really rich no matter the fuel pressure
