Re: two cylinders won;t fire
If you have already replaced the plugs and wires, 1st check that all connectors are properly attached to the coil packs. if that is all ok, you should change BOTH coil packs. when they begin to go bad, they will only send spark to one plug.

Coil pack connection is physical: Coil 1 to Cylinder 1, 2->2, etc.
I am not sure if this is your question, but firing order matches spark to TDC (top dead center) on the power stroke. The design of the crankshaft determines this.
1-3-4-2 is common for most straight 4's. Cylinder 1 is closest to the crank pulley. I believe your coils are 'waste spark' which means it will fire two cylinders at the same time. When the coil fires, one cylinder is on the power stroke and is wanting this spark. The other cylinder is on the exhaust stroke at this time, and thus the spark is 'wasted' on that cylinder. But a cylinder with exhaust gas has high impedance, so most of the energy is delivered to the intended cylinder.
If your question was 'should I just connect 1->1, 2->2, 3->3, 4->4' [ yes!] vs. ' should I try to connect coils following the firing order' [no] then the answer is the first. The trigger wheel determines which coilpack fires when, you just need to hook up the wires number for number.
1 coil pack is for cylinder 1 & 3 . The 1st & 3rd....moving back from the belts. 1 is on the top, three on the bottm of the coil. 2 & 4 should be the same, 2nd cylinder, 2nd back from the belts & top on the coil pack. 4 the last plug & lowest on the second coil pack. PLEASE NOTE: , A Handyman's Service manual, from an auto store can VERIFY THIS. My last experience was with the 1987- 1991 GM "Quad" 4 engines. One of the other experts on "FixYa" corrected a mistake I made on a newewr model. SO I WOULD CHECK this advise to A MANUAL. I was wrong on the other one I answewred, & do not want to add to your frustration. I have looked around my textbooks, I do not have one on that car, I have given it away.
Firing Order on 2.2 liter: 1-3-4-2
Cylinder number: 1-2-3-4 from passenger to driver's side
From the coil from fire wall to radiator: #1 coil 4-1 #2 coil 3-2
Good luck and this should help you get your car running 100% again.
2.3 and 2.4 has idi ign.syst. mounted directly on top of plugs,2.2 coil pack cylinder numbers are marked on it,from left of elect. connector on coil pack is 2-3-1-4where spark plug wires go,on block, cyl. from drive belt side is 1-2-3-4,timing firing order is1-3-4-2
you can test it but removing wires on the coil. they should have same strength as 1 and 4. if they are weaker then you have a bad coil. if nothing happens your have a bad module.
if you want put the 1,4 coil on the suspected bad tabs on the module and see if spark is same strength.that should do it. you pretty much did the right thing is swaping with what testing equipment you have to work with.
its most likely a bad module though. very common. when you test something always have someone explain how its tested and how it works.
The reason I'm asking this is because a dual coil fires BOTH plugs at the same time. If one plug doesn't fire right, the other won't either, even to a point that neither does. Kepp the coils where they are and swap the plugs and wires and see if you have a change. Let me know
