If the same coil pack runs cyl 1 and cyl 2, then I would say yes. If the 2 cylinders are on different coils, then no.

Yes on the toyota v6s there is 3 coil packs on the left, each pack has an igniter, I think my igniter in the number 1 cylinder went bad, or its an injector problem.I dont have a stethascope, going to give a listen with a screw driver for the click click.
In a few mins im going to go and switch coil pack #1 with the # 3 coil pack and clear all codes, I hope the mis follows? Thanks for the advice I will let you know what haappens as soon as im done.
