There is a very chance that it has jumped timing, I can’t remember does that engine have a timing belt or gears? If you can tell me that I can tell you how to check it
The flashing check engine light would mean that the engine is misfiring, If you have a scanner, use it on the diagnostic port of the engine to check for the error code to get which cylinder is misfiring and if there are other errors that needs to be checked.
If the engine is not missing now or running rough,The code may be an old one stored in the computer, The code for Evap usually comes from someone getting gas and not tightening the fuel cap so it clicks at least four times.
TRY REPLACING THE CRANKSHAFT POSITION SENSOR..HAVE SEEN THESE CAUSE MISFIRES AND LOW VOLTAGE DTCS AS PCM THINKS VEHICLE IS NOT RUNNING..ALTERNATOR MAY NOT BE PUTTING OUT PROPERLY
OBD II 300 Random/Multiple Cylinder Misfire Detected
When the misfire monitor detects a misfire, it will trigger the check engine light with the specific cylinder number as the last digit in the P030X code. For instance cylinder 1 misfire is P0301, cylinder 2 is P0302 etc. In this case we have either multiple cylinders misfiring, or the computer simply can't determine the specific cylinder, and as such we are left with the P0300 in computer memory.
Possible Causes:
Fuel injectors, related wiring, sensors and computer issues Running out of gas, or poor fuel quality Evaporative emissions system (EVAP) concerns: fuel vapors leaking into engine Incorrect Fuel Pressure EGR system concerns: leaking EGR valve or restricted ports Base engine concerns: low compression, valve train problems and timing issues Ignition system concerns including, but not limited to: Faulty spark plugs Faulty coil or related wiring Ignition module or related wiring issues Ignition related sensor faults or wiring issues
11= Timing belt skipped 1 tooth or more from initial learned value,
Intermittent loss of either camshaft or crankshaft position sensor, No
crank reference signal detected during engine cranking for dodge odb readout. Hope this helps.
