Symptoms may include:
the engine may be harder to start
the engine may stumble / stumble, and/or hesitate
other symptoms may also be present
CausesA code P0301 may mean that one or more of the following has happened:
Faulty spark plug or wire
Faulty coil (pack)
Faulty oxygen sensor(s)
Faulty fuel injector
Burned exhaust valve
Faulty catalytic converter(s)
Running out of fuel
Poor compression
Defective computer
-----------------------
I didnt notice any change in driveability, car was not harder to start or anything like that. Tank was full to the top of gas. Im leaning towards a dirty EGR, or Cat. Plugs are about 5000Miles old, and are NGK Iridium step colder.
Any other ideas?
