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.

Check your alternator see if you have a drop in voltage on your tack,then it is the problem.I too was a victim of high price tune up and still had a problem with a misfire.and cover your coil pack with a piece of rubber water run of onto your power pack .Another thing is to use a silicone spray on all wires.

I have a 97 ford thunderbird with 4.6 v8 codes show cylinder 1&4 misfire I have changed plugs wires maf sensor and it ran fine for a luttle bit then started again


1 and 4 show to be on separate coils. Check to make sure the plug wires near the 1 and 4 wires are not touching as this can cause cross firing among cylinders.

I have a 97 thunderbird V6 3.8L that is misfiring in cylinders 2 and 6. I tested all the plug wires at the plug connection with a calibrated tester, there is no spark at the plug. I have changed the plugs,...


Did you replace the coil pack or just verify 12 volt power to it? if both old and new coil packs have the same issue, (no spark on 2 and 6), then the harness to the coil pack has broken wires or bad connection(in the connector itself), or the computer is faulty. I believe each plug wire tower on the coil pack has it's own signal wire in the harness. Understand that the towers are "paired" together.
For example, cylinder layout.... 1 - 2 - 3
4 - 5 - 6
Depending on the firing order and the actual layout of your cylinder's the above layout would mean
1 and 4 get the signal to spark,(at the same time), even though 1 is on its power stroke, and 4 is on its exhaust stroke. Hope this is clear as mud!

First thing is to verify everything you did!!!!! verify wires are on correct plug and coil tower using a diagram for your engine. Next look for a vacuum hose you knocked off or forgot to put back on. My money is on a crossed up wire! good luck!!

I am assuming that you have a V6 Engine because 1, 3 and 5 would be on the other side of 2, 4 and 6. A Striaght in line engine would have them all in a row.

But another way to locate your spark plugs would be to find your Spark plug wires and follow them to the spark plug.

Good Luck
