What is going on with my 2.7??
Alright here goes nothing!
Bought this stratus from a guy and it had a horrible rod knock. Swapped the motor (forgot to see what car it came out of!) well with new motor came old problems. The car will start cold no problem as it begins to run for a minute or two it will start to bog down like it is drowning in fuel (i can smell the excess fuel) the throttle body then begins to suck in air like its supercharged and idles LOW LOW. now for my questions and hopefully some input. and Check engine light will come on about egr and purge solenoid.
1. Coolant Temp Sensor is acting crazy and is not reading right when running, It will read right when in run position/car off but not when car is running it will drop to 0.
2. Could It possibly be pcm such as putting a wrong motor/pcm combo together.
3. Other sensor that could be associated with what is going on.
----------------------------------
Things done....
1. Changed 02's (NTK)
2. Cleaned Throttle body, Idle air control, MAF
3. Cleaned EGR tubing/bottom of plunger.
4. Checked ground for ECT and ran new line.
5. Checked ground for 02.
6. Checked 02/ECT to PCM wires.
