When you get a po300 code and the check engine light flashes it to let you know to turn off the enging because you are starting to damage the catalatic converter, I screwed up mine by driving it it was a bad cam sensor
You must have an engine scanner to do that.
That REQUIRES an ENGINE SCANNER to do that.
it depends on the engine but check where the lower hose ends closest to the engine
NO!!!
Yes but, if the light is flashing no.
See link below.
It might be that you did not tighten the gas cap enough.
It is on because the ECU has detected a problem with the emissions system.
steering weel collumn, check autozone
Check engine timing
It will run, But not right and the check engine light will come on. It needs the converter.
You can buy the check engine computer and the book comes with it. I know, I bought one. When your check engine light comes on, you plug it in and check the engine and it will give you the code and you look in the book for that code and it gives you the answer.
