P0300 = Random/Multiple Cylinder Misfire Detected
The misfire detection monitor, a software strategy built into the computer, is designed to detect an engine misfire. The computer can also normally identify the specific cylinder in which the misfire has occurred. A misfire is nothing more than a lack of combustion, which can be caused by poor fuel quality or metering, low compression, lack of spark or unmetered air entering the engine. There are other possible, less obvious causes as well, such as uncommanded Exhaust Gas Recirculatin (EGR), flow. 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

DIagnostic Help:
To diagnose a P0300 trouble code we begin by checking for proper fuel and ignition system operation, and then follow up with the less likely causes listed above, such as EGR and EVAP system problems. New style coil on plug applications have a high failure rate, and can be concluded faulty by swapping to another cylinder and checking to see if the misfire moves to that cylinder. This is a quick check if a capable scan tool or oscilloscope is not available. Always make sure the basic maintenance is done first and that things such as the fuel filter, air filter, spark plugs and spark plug wires are in good working order, as these are all possible candidates for a problem. If necessary, check for wiring and component concerns.



P0353 = Ignition Coil C Primary/Secondary Circuit Malfunction
This vehicle actually has a common issue with this code. Unfortunately there is no recall for it but there is a solution. Check for broken wires at the coil pack connector. Lightly pull on the wire harness and see if the engine reacts with rough running. Repair the connector wiring and recheck.

Also, like reference information, can check this ARTICLE.

Hope helps.

Have you checked your spark plugs and wires? They may need to be replaced or the plugs may need to be cleaned or they may be gapped incorrectly.

My service engine light is flashing.the van is also running rough.1996 town and country van over 200,000 miles but maintained well


On yours, it's a misfire. Plug, wire or coil pack. Have the codes read. this will tell you where to look. 301 is 1 cylinder 303 is # 3. and so on. Pull the wire off the coil, have it close, no spark, replace the coil. Spark, do a tune up. Plugs and wires.
