Question about 2004 Chrysler 300M

1 Answer

Chrysler jerks at 2500 rpm

My Chrysler jerks at 2500 rpm. The engine light is on as usual, with the same codes for cam and crank. The cam/crank/wiring have all been replaced probably 2 times each. For over a year and a half I've been trying to have them investigate the problem. Light still comes on, car jerks, and sometimes gives me problems starting. Unfortunately, this doesn't happen usually when I take it in for the guys to check it out. Any clues what the problem might be?

    I forgot to list that all timing components have been replaced as well as the harmonic balancer.

SOURCE: the problem i'm having with my concorde is when

You obviously have connection somewhere in your OBDII system that has a intermittent open, short, or short to ground. OBDII is the system that monitor's all emission's "sensors" throughout the car. This is caused by the above wiring snafu or a sensor itself is trying to go out....Think back to previous repairs that have been performed on the car. does anything coinside with your problem? If so, go back to that area and inspect the wiring and such. Say, an intake gasket was changed out,...I would inspect everything around such repair...1. Throttle position sensor, map sensor, Idle control solinoid, intake air sensor, cam sensor, Etc,etc. You see, these sensors are all located on or around your throttle body, which of course is located on your intake. You follow where Im going with this??? the cam sensor is not on your intake, but the wiring harness which houses the wiring for these sensors could very well contain the cam sensor wire as well as others.... Check it out and get back with us......

2 possible problem come to mind:

  • Bad ignition switch; faulty switch will occasionally make contact but not every time
  • Bad starter; less likely but possible; a bad starter will function when it's cold but when it heats up, takes much more power to make it work
I hope this helps with your problem and wish you the best of luck. Take care!

My car engine stop running suddenly without any warning in neutral gear position, although I've check using OBD 2 reader there's no error detected. What usually causing this problem?


Hi

have you considered the ignition module that the coil pack sits on because that will cause your motor to randomly stop with out warning.

also the crank and cam angle sensor smay need to be considered depending on the vehicle

Eng starts hard,runs good until the rpm is over 2200 then it stumbles my input voltage on the cam sensor is 5volts ,on most cars i've read should have 8volts where


Both crank and cam sensors have a 8 volt reference I have found the wiring melted together where it cross over transmission shorting out the signal. also test your reference voltage at the computer with circuit unplugged at sensor watch meter and wiggle wiring going back to computer this will help find faulty area.

Have you ever replaced the timing belt?? If not the problem is likely to be a loose worn out timing belt. A floppy belt will play havoc with the sensor signals and trigger a check engine light and a camshaft sensor code.
