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?

 

P0300 Causes (* = Most Common)

• Faulty or worn spark plugs *
• Faulty spark plug wires or coils *
• Distributor failure *
• Faulty fuel injector *
• Vacuum leak
• Low fuel pressure
• Camshaft sensor defective
• Crankshaft sensor defective
• Engine timing off
• Leaking head gasket
• Low engine compression
• Poor quality fuel

 

another weak link on Fiat Chrysler's are the cam sensors and crankshaft sensors, I would replace the cam sensor and try it,unless you wanted to take it in for a scan,they can do a wave pattern on the sensors, either sensor will cause your symptoms .. good thing is you eliminated the tune up.. it can also be your ECM, but the sensors are more likely to be the culprit
