I have a 99 t/c with a 3.8 liter engine. It started with a misfire when in idle and also when driving. I checked it with the code scanner and it says misfire 1 or 4 with code PO300. Can someone tell me what this code means and how to fix it.

 

check the basics spark and fuel

 

Thanks chrysler tech. Do you have any idea what code PO300 means?
