I have had my Crossfire for several years now, and love it. Last summer, it developed a lifter making noise from time to time. I took it to Chrysler to have it diagnosed, and they suggested replacing all of them. So, I scheduled it in for last week, and they replaced them. I picked it up of Friday , and it ran fine. I drove back to work, which is only 3 miles away. It sat for a few hours, and then I started it up to take to storage for the winter. I went about 300 ft, and it made a sound like shutting off the motor with the clutch still out . Like the engine turning without it running. It also vibrated. I tried to start it back up, and it ran but shook violently. Had it towed back to the dealer, and as of yesterday afternoon, they couldn't find anything, other than the right side bank being dead. They have checked everything that they have done, checked all sensors, and electronics. Everything says it should run, but it doesnt. They were writing Chrysler last night, to get any possible input. Anybody ever have this issue, or any suggestions on this matter. Thanks for any Input on this matter.

 

Camshaft out of time? That would fit, or a dropped lifter, but that would just be 1 cylinder. Pull the valve covers, pull plugs, look for damage. I don't know how the fuel rails are setup, could you lose fuel to 1 side only?

 

Good possibilities. The Dealer Mechanic has rechecked everything, and no damage to anything. I looked at the plugs myself. all OK. nothing wrong with rockers, or new lifters, Timing is good. Injectors working properly. Everything checks out OK on the diagnostics, and says all good , but still rt. side dead. They are contacting Chrysler to see if they can shed light on the subject, even though it's at a Chrysler dealership now.T hanks

 

Could you undo one of the plug wires on the dead side and install a plug into it and hold it against the valve cover and see if there is spark ?
Only thing that makes any sense to me, although very little.
I can't see how 3 coil packs went bad together, or how the transistor drivers in the PTCM all went bad for all 3 coil packs.
Only thing I can think of is the the entire coil pack harness for that side got cut.
I guess the cam sprocket is keyed, it's possible that sheared and that side's cam is out of time.
If you have spark, then the cam is about all that's left.

 

My guess would be that it is cam related. I don't know how but it sounds like that side cam is not right, have that checked.

 

On that note, isn't this an "interference" engine ?
If so ( and I think it is ), if the cam has indeed somehow slipped timing and no damage has yet occurred, it could well happen if the cam slips any more.
Bent valves, holes in pistons, you name it.
Don't mean to overly alarm you, but better said now than later when you find out the hard way.

 

Yes, this issue needs to be addressed immediately! Considering that there was work done on the valve train, a timing issue is certainly within the realm of possibility.

 

Thanks for the replies everyone. After the dealership contacted Chrysler, and fed them all of the info, it was discovered that it was not just the Rt. side but both sides. It ended up being my MAF sensor. Not only was it reading incorrectly for the air, but also for the temp. it was adjusting for -160 temp, and was flooding the engine with fuel. Should be repaired in the next few days..

 

Glad to hear the problem is being addressed and you'll be back on the road/
