ok i hav replaced distributor cap n rotor, leads, plugs, fuel filter, crank angle and mass flow meter and the problem just gets a lil bit better but a lil diffrent at the same time. now sometimes it will run like a dream a but as soon as the engine is under load i can smell unburnt fuel real bad now occasionally while idling it kinda drops tryna stall n if i accelerat itl run like shit with a tinge of black smoke but after sum reving will come right again. in this last day or 2 iv been just driving along and it dies acceleration doesnt work , stinks of fuel until it stops then after a min will start and drive no problem until it decides 2 happen again completely at random....anyone please got any ideas im about 2 maybe replace the power transistor next 2 the distributor as iv noticed it getting rather hot but iv only had it six months and just cant seem 2 get it running smooth all the time
