PO300 is a random misfire. Meaning it is not just missing on, say cylinder #1, but it missing on all cylinders at random intervals.
Check for vacuum leaks.
It can be plug wires arcing across each other.
Can be intake manifold gasket leak.
P0300 is a random cylinder misfire. Ensure engine is properly tuned.
One way would be for the check engine light to illuminate and spit out a code P0300 for a random misfire.
P0300=random misfire. If this is the only code displayed I would start with the basics, check the spark plugs, the fuel filter, then progress to a fuel pressure test. Also check for fuel contamination (water).
That is the check engine light.That is the check engine light.
Bad spark plugs can have a variety of effects on the performance of your car's engine. Signs of bad spark plugs include a rough idle, engine hesitation, hard starting, check engine light illuminated with a DTC P0300 and reduced engine power.

The service engine light is the same thing as a check engine light.
If you have driven through water and the check engine light in your vehicle comes on, you should take your car to your mechanic. You will want to have your vehicle checked for any damage caused by the water. Probably will find that the ignition (plugs, wires, etc) got wet and triggered a misfire code (P0300). Allow the system to dry thoroughly and when the system detects there is no misfire after a few drive cycles the check engine light will go out.
The check engine light is the light shaped like an engine, or the light that states Check Engine (Soon). If this light comes on, it is time to see what the issue is with the engine.
There are sensors all over the engine that can turn the check engine light on.There are sensors all over the engine that can turn the check engine light on.
Yes, the Service Engine Soon light is the same as the Check Engine light.
The check engine light does not generally have anything to do with the check oil light. The oil light just indicated it is time to change the oil, while the engine light indicates a problem.
