p0300 means random misfire, and the engine light flashes because there is a problem with to much fuel, that can damage your catalytic converter, due to damage injectors, or map problem
goto engine-codes.com there is info on them lots of it and how and what to check the po300 is a random miss fire can be spark plugs coil fuel injector air leak and more it tells you what to ;look for ect. ok good luck
po300 is a random misfire, a P0300 doesn't tell you specifically which cylinder(s) is/are mis-firing, nor why. If it was a po302 this means its #2 cylinder thats misfiring,ETC, But po300 could be any one of the cylinders. check plugs, wires, fuel injectors, Etc. Good-Day!
The P0123 means Throttle/Pedal Position Sensor/Switch A Circuit High Input. The P0300 means Random/Multiple Cylinder Misfire Detected Clear the code with OBD2 code scanner. If it comes back on, you
still have an issue.
These are misfire codes.This means that your vehicle is missing.The 300 is a random misfire and the 305 is for cylinder 5,and the 306 is for cylinder number 6.Check the plugs if they are good then you could have bad coils.They are top of the plugs.Hope this helps.Good luck.
The po300 is a misfire code.This means there is probably a plug,plug wire,ignition coil,or ignition module.Check the coil towers one at a time.These are know for corroding.If you find one that is corroded then replace the plug wire also.Po171 is a lean condition code.The po300 could be causing the po171.If you have not had a tune up Now would be a good time.Hope this helps.Good luck.
I have tow of the three requested codes. po300 is misfire detected at multiple cylinders. See po301-306 represent the cylinder # misfire. So 301 is cylinder #1 misfire.
