What up Cali folks.
My poor 2007 SE 2.0 is having a P0300 Random Misfire issue.
Monday, the car lost all performance and went into limp mode, flashing CEL while driving on the interstate.
I parked it near the next exit and pulled the codes. (I keep an ODB2 reader on hand)
At that time it was showing the code for Crank Position Sensor circuit failure.
I reset the faults codes, pulled the negative battery terminal and let it sit overnight.
After running around town to find the part, I replaced what looked to be the OEM sensor.
This car has served me well and is currently sitting @ 220,000 Miles.
After installing the new sensor, restoring the battery power and starting the car all was good.
No CEL and running well.
I drove about 2 miles and up pops CEL with error P0300 and limp-mode.
I reset the codes again, pulled the power and let it sit for 30 minutes.
Same status P0300.
What's strange is that after resetting the codes and starting the car it will idle perfectly firing on all 4 indefinitely. (Or at least the 10-15 minutes I've let it sit there)
I even tested each cylinder by disconnecting the coil on each plug to ensure it was dropping the cylinder.
Each disconnected plug reacted exactly as expected, no fire, plugged back in the cylinder fired again.
The P0300 only pops up when you attempt to get it to 2,000 rpm.
I'm able to monitor some of the simple features of the engine with the code reader I have and an application on my PC.
Tonight I'll have a chance to get my meter out and test fuel injector power and\or fuel pressure during increased throttle.
Does anyone have 2-bits they want to throw in?
Other than this the car has been perfect with no other issues. :-\
Maybe fuel pump issue, Cam-Position-Sensor?
Thank you very much. -Chris
