At my wits end!!
 

My crossfire has again started acting weird!!
The symptoms are random and as follows:
1) All dash lights on while driving, at times the shift position indicator reads "P" while in D. When this happens the car is struggling to reach 30mph
2)Coolant, oil, Check engine and BAS flicker while driving.
3) Sometimes it starts after disconnecting the battery, sometimes it does a partial crank then nothing.
No codes present at the time.

RCM has been modded bu DJ, Batt and alternator are new and have been checked. Voltages are stable.

Sounds like a flaky ground connection, battery to frame, or engine to frame.

Re: At my wits emd!!
 

battery to frame is good not really a voltage drop there. Where is the engine to frame connection?

Re: At my wits emd!!
 

Upon researching it seems ill have to add one. I had an issue like this before on a RADAR. I'll give it a shot.

Re: At my wits emd!!
 

Let me add, no problems starting it now that it's cooked off

Re: At my wits emd!!
 

Driver side, bare copper mesh wire.

Did a chat with DJ very informative, I learned a lot about the RCM. Led me back tui the CPS. When I push the wire towards the front of the vehicle it runs fine. When I push it thi the back it dies or the lights all come on, fan speeds up, etc. Going to replace the sensor first as it's not a Bosch.

Please let everyone know the outcome.

Changed the CPS; A CPS code, trans range code and serial data link code popped up. I drove it for an hour all codes cleared. It's looking good so far.
