Question about 2008 Dodge Grand Caravan
Anything to indicate possible combustion gasses blowing by badly seated spark plugs? Any carbon soot around or even through the middle of the plugs?

Over voltage is the main reason for this problem. Run the fault codes to check for sensor failure. Remember that coils operate on a pulse and the current used is kept low but if you leave the ignition on ( run the radio-fan,lights etc with out the engine running then the current will overheat the coils/packs.

I hate to tell you this they really can not do anything they may just make sure its all pushed in/ What happens is plastic and plastic meet and when they shift it causes noise even if you took it back to dodge they would take it out and because all the snap ins are plastic it could make it worse I have seen that happen If you took it back to dodge atleast it would be noted every wherever you take the vehicle so thats the good news but its under warranty / Please rate my response Thank you very much

Number one and four are fired at the same time on a single wire from the PCM. Look for it to be intermittenly grounding somewhere along the route to the coil. You can wiggle the harness with the engine running to see if you can duplicate the miss. This will help to localize the area where you need to look closer. Look at areas where the harness crosses brackets or lays across areas like the transmission. Long term vibration can wear a small hole in the insulation causing intermittent problems on any circuit. I hope this helps.

If you have replace new cam sensor with no sparks and the coil are good putting out 12 volt, my guess would be the computer it self faulty. cam sensor sense the cam turning and send info to computer telling computer to disperse the charge from the coil pack to the plugs assuming relay, cam sensor, coil, plugs, and wires are good. make sure the cam sensor is put in properly and position.

check pulse on coil pack conector with noid light ,remember cylinders 1&4 fire at the same time. check pulse while cranking. most likely you have a bad computor or a broken wire

Testimonial: "most likely the problem"
Since you are still under warranty, I suggest getting your transmission checked at a dealer. We had to get ours replaced at about 28M miles. It was making wierd noises, especially in a parking lot at low speeds and when turning slowly.
There is no dipstick for the transmission fluid on our model :(
If you recently changed tires, then that could possibly be the noise too.
