Check engine light came on after starting to misfire. Code ran bad plug #4. I had just changed all plugs and wires because of misfire. Went in and #4 had never fired so I replaced #4 coil pack and plug. still running bad. Code ran #3 coil pack. I replaced that and plug. Still running bad and code still says #3 coil pack. Replaced that two more times with parts from different dealers. Still running bad and code is the same. In the mean time my ac has stopped working also. Could this be a computer module problem?

check to make sure #5 spark plug wire isn't bad,make sure you have not wired it wrong from changing plugs. You should purchase a chilton manual if you haven't already

You could have a bad coil in the back cylinders. Oil in the plug holes will short out a COP (coil on plug) in these engines, is is a known issue in these (Ford) engines. Do the same routine for the back cylinders, and you should also plan on replacing your valve gaskets/plug seals.

If you didn't use the OEM (original parts from dealer) That may be your issue. I've seen it before. (Specifically Nissan's)
If you can, you can Ohm out all of the coil packs and see if they are all similar. (A small difference can set an engine code)

It's very possible that you have either a vacuum leak on the intake runner to that cylinder, or a faulty or plugged injector.
