Dodge 3.7 V6 2007 Model

Engine light comes on, and replace COD's, Plugs, etc. Not long after big engine light is flashing. Vibration starts and gets worse.

Showing C6 is not firing. From what I have researched is the rocker arm could have fallen, but THE ENGINE vibration is very heavy.

Any experiences here?

 

I will move this to the 3rd Generation Dakota sub-forum.

 

I had a problem like that once. It was right after I had washed the truck. I washed the under-body pretty heavily and doing so I sprayed some parts of the engine. Well water somehow got under the spark plug coils (which are super sensitive to moisture). Well a couple drops of water caused 2 of my 6 cylinders to stop firing. I sprayed some compressed air in them to dry them out and they worked perfectly!

 

I had a similar experience related to wet coils. I ended up removing all 6 coils, all 6 plugs and baking them in the oven on 200 degrees for about a half hour, until there was no visible moisture. Problem solved!

If you dropped a rocker or some other valvetrain damage, I would imagine the noise would be horrifying. Hard shaking and missing = no spark. Possibly a misfiring injector, but my problem was 100% spark related.

 

welcome to the forum! How many miles on the truck? What is the code that it is throwing? Never heard of a rocker arm falling off. Back up and start with basics. Good advice so far. Vibration could be completely independant from the CEL. Start with telling us the code you are getting...if that is cylinder 6 misfire, check this thread about a cylinder 6 misfire...
