Engine light on P0300

Question

I have a 2006 Lexus ES330 engine light misfire code P0300

Answer 1

Hi there,

The P0300 code means there is a misfire on more then one cylinder, or that the computer can't figure out which cylinder is misfiring specifically. Usually when this happens the computer will eventually figure out which cylinder isn't firing. In the meantime check the age of the plugs, the fuel for water contamination and check for vacuum leaks.
