That issue usually is coil pack or power transistor or happen to have 2 bad spark plug wires

swap out the plug wires with the ones that do work (unplug it completely and swap it so to not change the firing order.) and with the car on, unplug wire from valve cover if you c ark then its the wire. if you dont its the coil.

do one at a time.

its a process of elimination.

check the wires to the coil pack make sure there not cracked. But most likely when no spark in 2 cylinders power transistor burned out.

It's the ignition module. I'm 100 percent sure because mine was doing that also.

Just because that was your problem, doesnt mean its his. Theres several things that could be wrong.

I understand your trying to help maxter22, but dont say its 100% this. Cause if he goes out and buys it, and its not it then hes out x amount of dollars. Better to give out an idea of what it is. Unfortunately his problem could be several things.
