P0300 is random misfire. the DTC light will come on when ranodm misfores occur or the PCM can not identify misifing cylinder.

Possible causes.

• Camsahft position sensor
• Low fuel ( less then 1/8 tank)
• Stuck open EGR valve
• Blocked EGR passages.

One or more EGR passages may be blocked or partially blocked. If this is the case the misfire detection monitor indicates the EGR port to check for possible blockage.
