[Scooter5.7340V8Hemi]

Been enjoying reading this forum for the last year or so but now I need to chime in and ask for help. All sorts of problems been popping up with my 2006 300c 5.7L V8 Hemi and with the codes I've been able to fix them all. The last issue now is when I go over 40mph and hit a bump the car either completely dies or goes into limp mode. In either situation the check engine light comes on along with red lightening bolt and sometimes traction control light. So far I've replaced all spark plugs, cleaned the throttle body, brand new accelerator pedal and sensor, new cam shaft sensor, new MAP sensor, new EGR sensor and cleaned the entire engine bay.
When the car hits the bump and either dies or goes into limp mode here are the codes:
P0344 Cam Shaft A Circuit Intermittent Bank 1
P061A Internal Performance Error Engine Torque Monitoring System
P061C Internal Control Module Engine RPM Performance

I don't really know too much about cars, mechanics is not my thing, and certainly no nothing about circuits. I've tried looking it up on the internet but I still can't figure out what I need to do. I know there are a few people on this forum who are like genius when it comes to this stuff. Could someone please help me and explain how I can fix this. Thank you so much!

No genius here, but the first thing I would do is go here to make sure there's no alternator recall on your car.

Then I'd pull the chassis grounds, starting with the ones next to the red "jump start" terminal, clean them well with a wire brush and alcohol, and put them back.

If that doesn't do the trick, check the engine block grounds. There's one on each side, coming off the cylinder heads.

Awesome, thanks a lot man, I’ll start there but first I just need to know what does the chassis ground and engine block ground look like?

Just make sure all your underhood grounds are clean and tight. Start with these:

So I actually cleaned those a few days ago, didn’t realize they were grounding wires. I don’t know if any of the codes I listed have anything to do with grounding but I would like to know what I need to do fix to clear the codes and drive my car without it dying every time I hit a bump.
