Update I found another forum. 300c forum. Thank you to the over 7000 viewers. I still have my black and blue, because she is a little bruised after 360000 or 370000, what is a few thousand miles give or take on my300c heritage edition . Having the manifold gasket replaced and some air conditioning parts and a wiring harness for the MDS system. Hopefully the parts I need will arrive soon. oops I posted this in the wrong thread first.

 

Hello all, I am waiting on a crank sensor that was shipped I am told and should have arrived last Monday. Well this is Friday and as far as I know it has not arrived yet.
This seems to be the shell game of which excuse will the delay be under now. A rep repeated to me a refrain I have heard in this thread perhaps or maybe a different thread.
This is the excuse that manufactures do not continue making parts for vehicles they no longer sell. Well if Cuban car folks can figure a way to get parts for 50s era cars you would think a billion dollar multinational conglomerate like Stellantis could find a way to get parts knowing they offered customers a lifetime contract of drivability on thousands of contracts. Hmmmmmmm
Oops my motor was running a little hot. Now some good news, when the moon is right and the night air sets in there are times black beauty comes to life.
What a sound a 5.7 Hemi with an exhaust having 343000, I quoted my mileage wrong in an earlier post ,makes. I have embarrassed a few unsuspecting individuals. I absolutely installed a power Torque transmission in this vehicle. I am not a liar and saying I claimed anything is insinuating it did not happen and that I am untruthful. Both are incorrect. Paragraphs who needs them really ?

 

Hello Joe, I hope you are still around!

 

update ******I do not know how to generate paragraphs in this forum. Hello, it looks like you are dealing with mechanical issues and what I am about to mention is a wiring issue but I figure this is an active thread so I would like to share in the hopes of ideas and suggestions. I have been dealing with a misfiring stalling issue off and on for a couple years. The dealership has replaced a lot of parts so I am not really that disappointed in the new additions. My problem is the dealership did not possibly really understand what the issue was. I have made some progress lately. They found a bad connection in the wiring harness that runs from my PCM to my MDS system. They said they pushed the plug together and it clicked like it had not been property seated or connected before. I had a new long block assembly installed through my Lifetime Maxcare warranty. The engine has always had a bit of a rough idle. ****** I have read that to get the amount of horsepower and torque out of this engine it needs to have a little bit of a hot cam, thus the slightly rough idle. I read that in the car and driver magazine as I recall. Well the engine also stalls again which it did in the past. It does this while idling in park or drive. It starts right back up and runs ok after this. I have new code which is P0688 and old repeating codes of P 4441 P4449 P4442 and p3449 these all have to do with my MDS system and the P0688 is the ASD relay not getting the proper power. I have replaced both catalytic converters and the PVC and a crank or cam sensor as I recall. I should say the dealership did the replacing and the installing of the long block assembly. The strangest part of this is the car would run fine for a week or so between the cutting out while under hard throttle. I have been babying it after being without my car from February till May of this year. I am a senior citizen with a lot of health issues and not having my car is a bit of a fix for me. MY car has about 40 thousand miles on the new engine at this time. It has run better this time around. I plan on taking it back to the shop again after a trip out of town. I believe this is a wiring issue due to the intermintantness of it. This was borne out by the fact the wiring was not connected properly. It seems to be better since they found the bad connection. I picked the car up after installing the catalytic converters and the engine light was still on and it had the exact same symptoms it had before. I immediately returned the car to the dealership and that is when they found the bad connection between my PCM and the MDS wiring harness. It has run better since then but as I said earlier has begun to stall again. Seems like a very strange situation to me. I suggested they replace the wiring harness and maybe the PCM ECM and the ASD perhaps. They will have to do a diagnostic of course and take pictures and send them into MVP for approval. I am hoping this eliminates the issues. The good thing is it has been doing much better but I am definitely not satisfied with the situation. Thanks for any suggestion and thoughts.
