Ok, here's the scoop...2 Fridays ago I installed an MPII, MP inlet, MP throttle body, 42lb injectors, and an adjustable FPR. The car ran awesome until this past Tuesday. Then it began to run rough and wouldn't hardly idle. I took it to the track on Wed, where it was still idling rough, but managed a 13.66 @ 102mph. The car was still running strong, but idling rough. I managed to take care of the idle, by adjusting the idle screw and putting a couple nuts on it to keep it from moving. The car began to hesitate upon full throttle though. It was running rich (lots of black smoke from the exhaust). I bought a fuel pressure tester and hooked it up and adjusted it. Kept trying it at different pressures and the car still hesitated and blew black smoke (although not as much). I adjusted it down to where the fuel pressure was about 40 static and the car finally felt strong, but still has a hesitation at full throttle. It still blows a little black smoke too. I also checked the oil and it has some small bubbles in it, but no signs of milkiness. The coolant looks a little cloudy, but nothing really bad looking. That's how the car sits as of right now. Any ideas?
