PO300 is a OBD II code for a random multiple cylinder misfire detection. Meaning any one or more than one of the engines cylinders is not firing at different times. Any number of malfunctions can cause this.To determine what repairs are needed, i recommend the engine to be diagnosed with a scantool and oscilloscope to monitor the crank sensor signal and other inputs to the computer. I hope this information is helpful.
P0300 - Engine misfire detected P1627 - PCM analogue to digital conversion malfunction. These 2 often come up together when theres a problem with the fuel level sensor. The sensor sits underneath the filter. Remove its connector. Resistance shold be 80-180ohm. You may also notice weird readings from your fuel guage.
After market spark plugs could be the problem.
Reinstall the old plugs and see if that fixes it.
This vehicle has an ion sensing ignition system and is real sensitive to the proper spark plugs. I would get the proper plugs from the dealer if the old ones work.
The codes P1311 and P1312 are ion sensing codes.
Tune it up and replace the 02 sensor that keeps setting the codes bank 2 sensor 1. Have your oil and filter changed right before you go for a retest to. That will clear up 3 codes P0300, 0155 and 0154. You might have to replace the fuel sending unit to get rid of P0463 but if the gauge works OK I'd leave it alone.
I am not an expert and I don't have the codes in front of me with the meaning but I can offer some advice and hopefully it will solve your problem. First keep the print out of the codes and take it/them with you. Have someone check the oxygen sensor. It's possible that all of the codes you are getting lead up to the computer (electrical issue). I sure hope this helps. Good luck and let me know how things turn out.
