Default P0300

2007 Sebring 2.4L

Engine stalled and check engine light came on. Turned key to restart car and it restarted right away. Check engine light constant on for a couple of minutes, then flashing for a couple of minutes, then alternating between constant on and flashing every couple of minutes. Did not stall again.

Checked codes, and P0300 is found.

Changed spark plugs (NGK properly gapped), coils, crank position sensor (genuine MOPAR), fuel pump module including fuel filter, checked all wires and hoses (everything looks good). Still, check engine light and P0300 keeps coming back. New battery 6 months ago.

What is the next thing to check to solve the P0300 code problem?
