Check the EGR valve. Replacing the EGR valve fixed my error code for misfiring. I also had to remove the battery cable for 5 minutes to turn off the check engine light.

I just need to know what the vdescription is for the code. the code came up P0300


PO300 IS THE GENERIC CODE FOR AN UNIDENTIFIED ENGINE MISFIRE. iT COULD BE CAUSED BY A SINGLE OR MULTIPLE CYLINDERS. BUT THE FREQUENCY OF THE MISFIRE IS NOT SUFFICIENT FOR THE MONITOR TO PINPOINT. POSSIBLE CAUSES CAN BE LARGE VACUUM LEAKS, EGR LEAKAGE INTO THE INTAKE MANIFOLD, EGR PASSAGE RESTRICTIONS, LOW FUEL PRESSURE, DIRTY FUEL INJECTORS, IGNITION COIL MALFUNCTIONS.
HOPE YOU FIND THIS USEFUL. HAVE A GOOD DAY.

1996 corvette didn't pass emissions codes po117 and po300 i just put new engine n tune up what could be wrong now


p0300 is usually a random cylinder miss-fire code, and i think that p0117 is coolant temperature sensor? Try replacing the sensor, could also be the reason for the other code, as a malfunctioning coolant temp sensor will affect engine timing.

P134, p0141, po300, po130 and po135. 2005 Sunfire.


Given that most of the trouble codes are for the O2 sensor, I think I would change it. The multiple misfires could be because of improper fuel/air mixture caused by a bad sensor. Disconnect the negative(-) battery terminal then change the sensor. Disconnecting the negative(-) should reset the computer and allow the fuel/air mixture to return to default allowing the engine to start.
P0130 - O2 Sensor Circuit Malfunction (Bank 1 Sensor 1)
P0134 - O2 Sensor Circuit No Activity Detected (Bank 1 Sensor 1)
P0135 - O2 Sensor Heater Circuit Malfunction (Bank 1 Sensor 1)
P0141 - O2 Sensor Heater Circuit Malfunction (Bank 1 Sensor 2)
P0300 - Random/Multiple Cylinder Misfire Detected

Trouble codes for saturn ls2 car is showing the following trouble codes. po300, po306, po451 p2bo3 and c112b


P0300 Multiple Cylinder Misfire Detected

P0306 Cylinder 6 Misfire Detected

P0451 EVAP Pressure Sensor Range/Performance

I have no idea what those last two are. Typo, maybe?

Your first two codes could be caused by old spark plugs and/or leaking plug wires.

Your EVAP code could be a bad fuel tank pressure sensor or a malfunctioning EVAP system. With that code, if you remove your fuel cap and get a whoosing sound, then it is an issue with your EVAP system not properly venting the tank. If you don't get that sound, then the tank pressure sensor is bad.
