i put a new coil on it from advanced auto , gp sorenson brand , but it may be bad as i have heard alot about their electric parts . i put the egr valve on and set the time back to zero . still has a miss though it seems to be not as bad but still their . i am going to try to change plugs to ac delco or any other brand your guy's recommend and i also thought i would try to put on a set of 8 mm wires and a better coils such as msd or hypertech , what do you guy's think . it seems as the miss is in the fire to me but i could be wrong . i appericate all the input from evryone . thanks silver100 . i will post as soon as i fix the problem and i appericate any help . thanks
