multiple misfire code... fuel filter? fuel pressure? what could it be? my 383 is throwin a misfire code on cylinders 1,4,6,7... its the ls1 block, oversize injectors, not sure if i should get a fuel pressure gauge and where should i get it? am i not getting proper fuel? for it to be a multiple misfire and it is not a total miss in normal driving, i was told it was probably a fuel delivery problem, but i am not tuned since i rebuilt the bottom end, so could it just need tuning? is it reading too little air and not injecting enough fuel or is it maybe the fuel pump or filter?
