98 gmc 2500 5.7 missing. Full electric tune up, two injectors replaced, still missing, after tune up, ran diagnostic check, #5 & 6 cyl missing, changed injectors, no change. Engine does'nt miss at idle or full throttle, it misses at about half throttle, or ie: at freeway speed, on flat road, half throttle, or maintaining speed.
