Hi I was wanting to see if u could help or just give me some advice!? I have a 2002 Chrysler 300M 3.5, It now has about100,000(give a little) miles on it. We have changed the Transmission,Speed Sensors(both),All 6 Coils,Spark plugs, Timing Belt,Water Pump,Thermostat,Oxygen(O2)Sensors(all 4), Fuel Injectors and the little bar that goes with them, Upper Intake Gasket, Radiator,and the Crank Shaft Sensor.Still the car is not running right, it says miss fire on Cylinders,and running to rich. It has a vibration when u let it Idol and its just not running right its VERY sluggish when u first take off or go from red light to red light like it wants to die! Do u have any Idea what could be causing this or think of anything else I can change that might fix this problem? Ive taken it to a dealer and all the done was charge me $100 and said they think it was the fuel injectors(I changed after they said that) and then before they can tell me anymore they need to break it down and then I will have to pay for Labor and their parts! So a dealer is out of the question again! I'm just lost on what else to do and I'm about tired of putting the money into the car but I look at it like when I finally get that last part that's messed up it will almost be a new car LOL. We had the codes read today 2-26-11 and they came up Camshaft sensor and Crank shaft sensor which we just changed both of them.Crank shaft on 2-19-11(which made a great diff for a little bit till CEL came back on) and then that led us to change the Camshaft sensor today2-26-11,and didn't know if we were going to make it home ! When I accelerated to above 2500 RPM's, the car sputtered and lost power but did not kill. I could drive it just as long as i didn't get above 2500 RPM'S. So we got it home and put the old Camshaft sensor back on and it is running again but still not great!Its still saying Misfire on all Cylinders,we tried to clear the codes with the computer that reads the codes and as soon as we turned the car on the light was back on (that's before we put old camshaft sensor back in)...My Husband is going to look at the timing belt to check and see if he has it off a notch so ma by that will get rid of the All cyl misfire,and where it is running rich. But once again im stuck on what else to do. Still dint know if the old Camshaft is bad or good or if we just bought a bad camshaft sensor (which im taking back tomorrow! ANY ADVICE WOULD BE GREAT FULL!!!!!
