If you are just talking about the codes regarding misfires, this can be triggered by inferior spark plugs. Stick with NGK or Nippon Denso for this car. If you are refering the to an actuall feel of a misfire, double check all coils and wires for tracking which will be white trails that indicate an electrical leak and shorting to ground(the engine block). Let me know which one.

these codes indicate there is a miss fire on cylinders 1 and 2 hence the 0301 and 0302 code the 1300 just indicates multiple engine miss fires. so anything that can cause these cylinders to miss fire need to be attended to in order to fix your problem.

When there is an engine misfire it could be gas or spark related. Or, the oxygen sensor may not be operating correctly, which controls fuel supply.

If there is a 'random misfire' then it could be an oxygen sensor causing the problem, as well, causing a rich mixture.

Good luck on this repair.

Check engine light is on and it reads Misfire on #2 cylinder. Also oxygen sensor bank2 sensor 1 and Bank 1 sensor 3 behind the converter. Engine running rough.


the engine miss fire can cause the other codes to set. you need to repair the miss fire and clear all codes after the miss is repaired then see if the 02 sensor codes return. the miss fire is probably a bad spark plug wire a good tune-up should take care of it ........HAVE A GREAT DAY

Engine miss fire


Engine misfires can be caused by a variety of anomalies.

Check the computer with an OBD-II Scanner. I just got one from Walmart for $98 plus tax, and it has English descriptions of codes that it reads.

It will tell you which cylinder(s) are missing and if you have any sensors that have issues or problems.

This is an invaluable tool for fixing engine misfires. Good luck to you.
