My buddy has a 95/96 4.6 t-bird, that is popping through the intake. It pop's through the intake when he is leaning into the throttle. We hooked a fuel pressure gauge and it is showing 30psi @ idle, and when he blip's the throttle the pressure hardly moves. If he keeps onto the throttle after the motor is done stumbling over it self the pressure will work it's way up to 40psi, and then he let's go it will fall to 26psi, and go up to 30psi when it begin's to idle normally...I told him it's retarded, and so is it's spark. If my plug wire location is correct for #1. The timing light is showing the notch 8-10 deg before the 10 deg BTDC mark on the timing cover...How the **** do you advance the timing? ... I also think that maybe the Air intake temp sensor -or- Exhaust temp sensor has something to do with it.....ANY HELP WILL BE WELCOME>>>>THANX MIKE
