well most likely it isnt either. ive never seen a bad ignitor. and all 3 coils going bad at once isnt likely either. chances are its just a bad ground. check the grounds that bolt underneath the intake manifold from the ecu. 2 diff clusters of them bolted to the same spot. always overlooked when replaceing the hg it seems. also should be a ground wire from the head to the body. thicker the better. 1 from the neg of the bat to the block, neg of the batt to the body. a small ground from the coil pack bracket to the head. make sure the cps is plugged in. that connecter even the tiniest bit loose causes issues. i would say strip the insulation off the cps wires on the engine harnes going across the head but with that few of miles they shouldnt be brittle and cracked idividually. ive had to fix that before also. like i said. i KNOW i can sort this out pretty quick in person. prolly in 5min. lol.
