If you changed and the injector and the coil and does not work change the spark that cylinder and see if comes to that coil voltage (positive and negative) and is less negative than if the PCM does not work that coil. Thanks good luck and opinions please

2003 sorento 3.5 cranks won't start code 300 302 304 306


The code 300 is a Random/Multiple Cylinder Misfire....a 302 is Cylinder # 2 misfire detected. ..and the same for 304 and 306..being 304 is cylinder 4 misfire and 306 is cylinder 6 misfire...All these at the same time normally is a faulty coil pack..,and or faulty coils...spark plugs.,plug wires.....It should be running horribly or barely ....However it could be internal losing compression.....It could just need a good tune up.....Disconnect battery before changing coils,wires..,or plugs in order to clear the fault codes.....

Misfire on #4 cylinder when accerating on a 2005 renderous


I would start with switching a coil, swap # 4 coil to another spot and see if the misfire moves, the coils on this van operate to cylinders so move it and see if the misfire changes then you know its the coil and if it does not then next thing is to check spark plug and wire, replace the plug and wire and if that solves it then tune up van, good day,

2002 saturn vue cylinder 1,3,5 misfiring when swapped coil pack it went away now cyl 2,6 misfiring.


having PO 304 = Misfire cylinder 4,PO 306 = Misfire cylinder 6, as I read above you have done the most. The thing that you have missed is to check whether the Catalytic Converter is faulty or not. To get an idea check whether you have a smell like rotten eggs at the end of the exhaust,you start having problems with cat and needs replacement. My advice before you go for a cat replacement is good to visit an MOT center and check your emissions and then you decide,

I have a 2008 dodge avenger se and my engine light is on and was flashing before. when it is in drive or park it turns off when i stop. i took it to auto zone and the told me that cylinder 3 and 4 misfire...


The best way to fault find in swap coil 1&2 with coil 3&4. If the fault doesn't change, it is possibly the plugs or something more sinister electrically.

Car keeps giving p0303 code.


Code P0303 means that there is a misfire detected on cylinder #3. This could becaused by anything from a worn out spark plug to a blown cylinder head gasket, a faulty fuel injector, a bad ignition coil, or a leaking intake manifold gasket. I have also seen this type of code caused by clogged-up EGR ports in the intake manifold on certain engines. "Freeze Frame Data" stored in your Engine computer along with the fault code is designed to help identify what engine conditions (high speed/slow speed, heavy load/light load, etc.) are producing the misfire. This helps a lot in identifying exactly what is causing the cylinder to misfire.

One way to eliminate some of the possible causes is to swap parts with another cylinder to see if the code changes.

If you have "Coil-On-Plug" ignition, you can swap the coil on #3 cylinder with the coil on #4 Cylinder and swap the #3 spark plug with the #2 spark plug. Then clear the codes and drive the car till the Check Engine (or Service Engine Soon) light comes back on.

If it still gives you P0303, then it is not being caused by the plug or the coil. It could be any of the other possible causes listed above.
If it now gives you P304, replace the bad ignition coil that is now on #4 cylinder.
If it now gives you P302, Then replacement of all the spark plugs is recommended.

I wouldn't worry about the 02 code it will clear when you replace the coils. to be positive that the coils are bad, swap them with another cylinder and see if that cylinder misfires. 90% of the time it's the coil. Let me know

2003 mercedes Benz C240 codes P0300, P0301, P0302 and P0303. Please, help me how to fix?.


P0300 Random Misfire Detected
P0301 Cylinder 1 Misfire Detected
P0302 Cylinder 2 Misfire Detected
P0303 Cylinder 3 Misfire Detected
according to this fault codes first mark ignition coils
3 ---------------- 6
2 ---------------- 5
1 ---------------- 4
RB-------------LB
this right banks and left bank, please remove Ignition coils with lids and spark plugs from right bank and swap with left bank, if fault code change as
P 0304 Cylinder 4 Misfire Detected
P 0305 Cylinder 5 Misfire Detected
P 0306 Cylinder 6 Misfire Detected
You can Identify it's a faulty ignition system then next swap ignition lids from ignition coils be careful each coils have two lids one short and other long bit deference and when you remove and fix it to the car keep in mind correct order because each coil two different fire for two spark plugs don't mix up, if you mix it can create the fault code.if you detect any fault ignition coils or spark plugs or lids replace that and also whether god or bad recommend to replace spark plugs, find the right that's most important thing, if this way couldn't found the any ignition fault next step is check fuel presser, when the engine running fuel presser must be around 4.5 bar without engine running must be 4 to 6 bar if the fuel presser too low need to check two different things one is fuel pump other is fuel injectors, in this case you can swap injectors from right bank to left bank and find is the injectors leaking, if not leaking faulty fuel pump.is this information helped you? if yes please leave a comment,

Recurring #2 cylinder misfire.


Hello Mr Fixit...If memory serves me right, the PO352 B fault code would indicate #4 cylinder coil and PO352 A for #3. The
Possible causes ...faulty spark plug...faulty spark plug wire..faulty ignition coil pack..faulty PCM...open or short in wiring from PCM to iginition coil pack. To accurately troubleshoot and determine the problem you will need an oscilliscope and a diagnostic scanner. Without these you are basically guessing as to the cause.
The ignition control module is integrated into the PCM and a faulty ICM can definitely cause this trouble code...and i have seen my share of faulty PCM's.
Hope this helps and the best of luck to ya.
