I have a misfire on # 6 plug on my 2006 Dodge Grand Caravan 3.8. no spark coming off of the coil pack when pulling off the boot. Coil pack does not appear to be repairable. Any other possibility?

if you cleared the code - fixed arc and checked their are no more arcs - and keeps coming back then problem can be a burnt or carboned valve --lifter -push rod --piston

No cylinders fire at same time. 6 & 3 must be from same coil-ignition coil C-that is the one with the problem. And the secondary circuit- that is the spark firing portion of the coil. Coils have a primary winding circuit and a secondary wire winding circuit. The secondary comes out of coil as the tower, or the spark plug wire tower -the business end of the coil leading to the plug.

You could have a bad new coil (happens occasionally) or the connection to that coil may be the problem-the connection where the coil snaps onto the coil pack assembly. Try swapping that coil (coil C) with another one there and see if problem follows the coil. See? Keep your plug wires the same, just swap coils with another and see if the new position for suspect coil causes other cylinders to misfire. If a different coil in that "C" position causes same code, then it is not the coil itself, but probably the base assembly that the coil connects to.

These ignition systems use what is called a waste spark, or exhaust waste spark system. The coil will send spark to 6 & 3 simultaneously, but since one is always on the exhaust stroke while the other is on the compression (firing) stroke, the exhaust spark is very weak, and all the energy from coil is directed to the compression stroke cylinder. It sounds crazy but it works great.

Since you say it runs bad just as before, that indicates the coil is not the problem, but something wrong with the base of the coil pack . This is where the wiring is directed to the coils.

My thinking is, if all the other cylinders have spark, the coil pack is faulty. I'd also change spark plugs and plug wires. Check good primary voltage to coil pack. I didn't think to look for dedicated ground, but, check that also, where applicable.

You didn't say year or engine. I worked on a 3.3l from the 90s. The coil pack is three separate coils and plugs 3 and 6 are one coil being no spark on rather plug. Most likely no signal coming in for that coil. The code is for the secondary circuit for that coil. It should be a pulsating signal

good question, most likly a spark plug or wire. but it might be a coil , to test it remove the plug wire from the coil and crank the engine there should be a good strong splrk if there is replace the plug and wire if not replace the coil.

Not sure exactly what they are but my guess would be the coil packs. Take these off and pull the boots up and then you can access your plugs. They will come off try twisting them free and pulling up as over time they can get stuck to the plug. I would also recommend changing the rubber boots also.

spray coil pack with windex and see if fire is jumping from it

Firts time swap spark plug & ignition coil between two different cylinders and read again if the same #2 cyl. misfires !
If #2 cyl. is OK and another cyl. misfires then spark plug or ignition coil is out of order and must be replaced.
If #2 cyl. misfires again then #2 injector must be checked !
If ignition coils & spark plugs (complete set for 6 cyl.) are replaced then you must check #2 injector !

we get remans bad out of the box......... good luck
