They're numbered like this:
Pass side: 2-4-6-8 Driver side: 1-3-5-7

Try changing the plugs or coils from #2 into a different cylinder. If, for example, after changing, you get a different code such as PO305, you'll be able to pinpoint the issue and cylinder its coming from. If you don't own your own code reader, autozone rents them out. Sometimes they'll lend it for free depending on who you get.

I have a 97 Dodge Ram 1500 with a 5/9 in it I put plug wires on it and now it's popping and it lost power and it had a code po302 and Po 307


The P0302 code means that the cylinder 2 is misfiring or is randomly misfiring. Start by checking for intake leaks and if no leaks are found the next step is to replace the spark plugs on cylinder 2. If the problem persist more tests needs to be done. PO307 is the same thing except number 7 cylinder. Possible symptoms - Engine Light ON (or Service Engine Soon Warning Light)
- Lack/loss of power
- Hard start
- Engine hesitation

P0300 code. Came up checked for spark troubles found nothing good spark good compression something is making the vehicle sound rough should I suspect a weak fuel pump anyone have a common fix


Borrowed from OBD Codes.com:
"Basically this means that the the car's computer has detected that not all of the engine's cylinders are firing properly.
A P0300 diagnostic code indicates a random or multiple misfire. If the last digit is a number other than zero, it corresponds to the cylinder number that is misfiring. A P0302 code, for example, would tell you cylinder number two is misfiring. Unfortunately, a P0300 doesn't tell you specifically which cylinder(s) is/are mis-firing, nor why.

A
  • the engine may be harder to start
  • the engine may stumble / stumble, and/or hesitate
  • other symptoms may also be present
  • code P0300 may mean that one or more of the following has happened:
    • Faulty spark plugs or wires
    • Faulty coil (pack)
    • Faulty oxygen sensor(s)
    • Faulty fuel injector(s)
    • Burned exhaust valve
    • Faulty catalytic converter(s)
    • Stuck/blocked/leaking EGR valve / passages
    • Faulty camshaft position sensor
    • Defective computer"

  • StarI suggest you start simple.... replace the plugs and test the spark plug wires. Make sure all connections are tight.

    Hi there:DTC P0300 - Random/Multiple Cylinder Misfire DetectedBasically this means that the the car's computer has detected that not all of the engine's cylinders are firing properly.
    A P0300 diagnostic code indicates a random or multiple misfire. If the last digit is a number other than zero, it corresponds to the cylinder number that is misfiring.

    DTC P0302 - Cylinder #2 Misfire DetectedA P0302 code means that the the car's computer has detected that one of the engine's cylinders is not firing properly. In this case it's cylinder #2.

    Symptoms may include:the engine may be harder to startthe engine may stumble / stumble, and/or hesitateother symptoms may also be present
    A code P0302 may mean that one or more of the following has happened:
    Faulty spark plug or wireFaulty coil (pack)Faulty oxygen sensor(s)Faulty fuel injectorBurned exhaust valveFaulty catalytic converter(s)Running out of fuelPoor compressionDefective computerPossible Solutions:If there are no symptoms, the simplest thing to do is to reset the code and see if it comes back.
    If there are symptoms such as the engine is stumbling or hesitating, check all wiring and connectors that lead to the cylinders (i.e. spark plugs). Depending on how long the ignition components have been in the car, it may be a good idea to replace them as part of your regular maintenance schedule. I would suggest spark plugs, spark plug wires, distributor cap, and rotor (if applicable). Otherwise, check the coils (a.k.a. coil packs). In some cases, the catalytic converter has gone bad. If you smell rotten eggs in the exhaust, your cat converter needs to be replaced. I've also heard in other cases the problems were faulty fuel injectors.
    Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

    Thank you for using FixYa, have a nice day.

    Reads codes of po300,po302,po303,po305


    Hi these are mis-fire codes ,
    P0300 is a general mis-fire detected code the others relate to specific cylinders,
    P0302 is cylinder 2 misfire
    P0303................3........
    p0305..................5........
    I would check your spark plugs first if Ok you need to make sure the coils are working ok for this you need an osciloscope to check output voltage if your not sure then take to a qualified mechanic with Cadilac experience it could be caused by an air leak,bad ECT sensor or even Mass air flow sensor ,codes only tell you the result not the cause

    Where is #2 cylinder on 2000 jaguar s type 4.0?And what is code p0302


    I recently starting having this problem also (only code p0305/308). That code means "miss-fire" on #2 cylinder. The #2 cylinder is the nearest cylinder on the right (closest to front of car on drivers side) if you are standing in the front of the car.

    P0132 code along with P0300, P0301, P0302, etc.


    check for intake manifold for vacuum leaks, use a can of spray carb cleaner and spray around the top of the engine, if you hit a leak the engine idle will change, P0302 is a miss in #2 cylinder (cylinder power output low, lean cylinder due to poss vacuum leak and other issues.). once again an O2 will not cuase a mis-fire.
