P0301 Cylinder 1 Misfire Detected. Can be bad plug or plug wire. Can also be a burnt valve or head gasket leak. On a 10 year old car, I would replace the plugs and plug wires. If the miss persists, run a compression check on all cylinders. If cylinder 1 is low on compression, suspect a burnt valve unless you are loosing coolant or engine is blowing white smoke. If white smoke or coolant loss is present, suspect a blown head gasket.
what does P0650 mean on a 2001 buick century
Trouble code P0730 means:Incorrect gear ratio
02 sensor problem
Trouble code P1860 means: TCC PWM Solenoid Circuit
If you mean pcm- the computer.
Im going to assume the code you have given is PO740 on the obd2 scan tool? PO740 is a TCC circuit malfunction
When the trac light is off, on a Buick Century, the traction control monitoring system is disengaged. It is recommended to have the trac system engaged on wet roads.
