Swap coil 4 to cylinder 1 and 1 to 4. If the misfire moves, you need a new coil pack.

Firing order is 1-2-3-4-5-6
Cylinders on the head with the coil pack are 2-4-6 so the other head is 1-3-5
Its difficult to tell by the diagram but the coil sequence may be 3-4-5-2-6-1

how to wire the coil pack

http://www.fixkick.com/look/odds-ends/jeep/2008-JK/slideshow/firing-order.JPG

Check this site I believe the black images is the coil pack firing order. I used a coil pack from a different model but had to open it up and change the firing order since the spark wires wouldn't reach for my 91 buick. You should have some knowledge about wiring before attempting that. Basically I just switched the wiring on each side inside the coil pack.https://www.google.com/search?q=buick+1991+park+avenue+firing+order&tbm=isch&tbo=u&source=univ&sa=X&ei=reisU9eSH9HioAThh4D4BQ&ved=0CC8QsAQ&biw=1440&bih=748

Coil packs do not have firing orders, engines do. I suspect you were given the incorrect part.

It sounds like a bad ground. The coils are grounded through the Ignition Control Module and yours may be defective. The replacement of an ICM takes about fifteen minutes and you can do-it-yourself.

check the fire to the coil pack if it's present then check the pulse to the crank sensor

Here is a diagram of the firing order for you 3800 engine. Cylinders 1 and 4 are misfiring because the operate under the same "Coil Pack" and the coil pack has unfortunately gone bad. O'Reilly sells them for between $30-50 depending on the amount of warranty coverage you want. To replace, simply unscrew the screws that hold the coil pack in place. WAIT before unplugging the plug wires. Place the old coil pack and new coil pack next to each other, unplug one plug wire, then plug it to that same port on the new coil pack. then do the same for the other plug wire. Then screw your new coil pack in place, and start you car. should run fine!

ARE YOU CHEKING SPARK OFF THE COIL TOWER OR AT THE SPARK PLUG END OF THE WIRE SOUNDS LIKE YO HAVE A BAD WIRE
