You can remove the suspect coil and switch it with a good coil and see if the two cylinders that were firing are now misfiring and the two that were misfiring are now firing.
If the coil pack is not working correctly then your car will be sluggish and should throw a misfire trouble code (check engine light). Usually only one coil will fail at a time. You can have the code scanned at autozone for free. They will also test your coils if you have them off the car. Always check your plugs and wires first before replacing the coil.

on the left side front of engine there will be 3 coil packs in a line. take the two screws off each coil pack and fold coil pack back and module will come free from under coil packs you will then need a 7mm nut driver to take loose wiring harness.try to remember to put heat displacement material on new module .it gets pretty hot there

you have to take the coil pack off and move it to the side thereis only a few bolts .Unhook front mounts real easy tilt engine ahead and there you go.
what is the number coil pack
careful if you do not know never turn engine over next to coil be advised
Losing power as if bogging down? My 98 Monte Z34 was doing the same thing only when very damp or raining. Was told it was an emissions problem. Turned out to be a crack in the ignition coil pack. Not sure about your muffler but mine actually is a small hole and will need to be replaced.
You're going to laugh! The firing order is 1-2-3-4-5-6. Looking into the engine compartment, the cylinders closet to you are, from left to right, 2-4-6. The cylinders closet to the firewall are, from left to right, 1-3-5. The coil pack cylinder sequence is: front coil(nearest to rad)5-2, middle coil 3-6, rear coil 4-1 Hope this helps
Most automobiles will not start with a nonfunctioning coil pack. The coil pack will cause the spark plugs not to fire.
