pretty much stock car, exhaust, 5% pully.. Starts hard about 70% of the time, sends out a lil black smoke and can almost smell pure gas..also when i'm driving, it bucks when i push it past 3/4 throttle.. I'm thinking FPR, because i have new 190lph fuel pump and filter, plugs, wires, TPS and coil. Fuel pressure is 33 at idle and 40 when revved, but when i shut the car off it slowly dwindles down to 0. So any help would be appreciated...I really drive her again soon!!
