One common cause for this problem is water in the spark plug tubes. This most commonly happens with aftermarket spark plug wires, because they don't seal the plug tube as tight as OEM wires. Pull out your plug wires one at a time and blow out any water with some compessed air.

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.

1996 olds cutlas supreme, 3.1 L has trouble codes PO171 and PO300. Any Ideas?


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.

Code po300 check engine light


The Po300 is a random misfire code where the PCM is picking up the misfires. The other two codes are lean mixture codes. More than likely these are due to bad intake manifold gaskets allowing unmetered air to enter the engine causing the engine to lean out and possibly run a little rough when cold

I have a diagnostic trouble codes p1768,po300,and a po420. what does this mean?


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.

po420 is Catalytic Converter Efficiency Failure
