Technical Description
Cylinder #1 Misfire Detected
What does that mean?
A P0301 code means that the the car's computer has detected that one of the
engine's cylinders is not firing properly. In this case it's cylinder #1.
Symptoms
Symptoms may include:
* the engine may be harder to start
* the engine may stumble / stumble, and/or hesitate
* other symptoms may also be present
Causes
A 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
Possible Solutions
If there are no symptoms, the simplest thing to do is to reset the code and
see if it comes back.
If there are symptoms such as the engine is stumbling or hesitating, check
all wiring and connectors that lead to the cylinders (i.e. spark plugs).
Depending on how long the ignition components have been in the car, it may
be a good idea to replace them as part of your regular maintenance schedule.
I would suggest spark plugs, spark plug wires, distributor cap, and rotor (
if applicable). Otherwise, check the coils (a.k.a. coil packs). In some
cases, the catalytic converter has gone bad. If you smell rotten eggs in the
exhaust, your cat converter needs to be replaced. I've also heard in other
cases the problems were faulty fuel injectors. | I*D
