already tried that... new plugs wires, tried coil, map and cam sensor from another car i have, i got ahold of a fuel pressure gauge and fould out in loosin fuel pressure, it doesnt just drop off though, it gradually drops from about 3.5 bar down to almost nothing ant WOT, when you let off it will go back up gradually, at idle it will drop about .5 bar then back up constintly, im thinking it might be either a regulator or fuel pump,
