So I Googled the causes of code po300 and it's a random/multiple cylinder misfire. So I went trough all the possible causes of the problem.
I have already replaced the spark plugs.
I replaced the coil packs.
I replaced the EGR valve.
I replaced the crankshaft sensor.
I replaced the camshaft sensor.
I replaced the throttle positioning sensor.
I cleaned the fuel injectors.
I checked the catalytic converters which they are good.
I checked for vacuum leaks. There were none.
I dropped the gas tank and checked the fuel pump which is good.
And replaced one of the four o2 sensors.
And after all of that it still keeps throwing the code.
So if you have any idea what this is or might be the problem with it I am all ears. Lol. I can't affordably take it to a mechanic right now I was just laid off. So any suggestions that might help me.
have the same problem?
