If the coils were drawing more amperage than the coil drivers in the module were designed to handle it may have destroyed the drivers .
If you're finding it difficult to service/repair your car, get one of those online manuals. You'll not have to wait for others to answer, or rely on mechanics and all. Plus i know a website that sells very cheap but very very good manuals online, without expiry i.e. for lifetime.
for this u can try reliable-store which is pretty good

It could be carbon deposits on valve seats keeping valves from totally closing. You can try getting you a can of motorcraft PM3 top end engine cleaner and get engine up to operating temp then remove one of the small vacuum lines from the intake and draw the contents of the can slowly into the engine.After you have drawn in the contents shut engine off and let it soak for about 45 minutes then crank it back up and let it run until it clears. Now it will smoke like a forrest fire while you are doing this so don't be alarmed,just tell the neighbors you are spraying for mosqitos.This may cure the problem. If not you may be looking at a valve job.
This can be verified with a compression test if this is what is causing it.

Does this motor have the equivalent of crank-trigger ignition? If so, is the sensor A-OK?

do a compression test, you may have a bend valve , I'm assuming its not getting overheating so I don't think its the head gasket..a compression test can give you the answer..hope this was very helpful...thanks

have the crank sensor check for erratic operation. if you have done all of that then there is nothing else. and they way the computer knows it is misfiring (if it is) false code maybe and could be bad crank sensor. good luck
