I have a 2000 XJ. I bought it was a motor that had been supposedly rebuilt about 20k ago. Long story short the car has been in the shop since November. The mechanic is havng trouble finding the problem so Im hoping to get some pointers. The engine has low idle when its cold outside and it misfires and it gets worse as the RPMs raise.
According to the mechanic one of the spark plugs is being told to fire twice by the computer. He replaced the computer and the coil pack. The car throws a couple codes one of them being P0391 I believe.
When I bought the car the sensor on the side of the motor(i believe thats the camshaft sensor), which is normally parallel with the motor was cocked off about 60 degrees. When you set it to the factory position the motor barely runs. Cam and crank sensors have both been replaced with OEM sensors. Im thinking that the cam possibly has a flat spot...any other ideas would be greatly appreciated.
