P0302 Cylinder 2 Misfire Detected P0303 Cylinder 3 Misfire Detected I suggest you replace all spark plugs, and plug wires. When you purchase the plugs and wires, tell the parts store the codes and ask them to reset the light after you install the parts. See where you stand after the repair. I would also run a compression test on all cylinders to see if you possibly have a burnt valve or blown head gasket, which is unlikely, unless you have symptoms of overheating or missing, especially after you replace the above items.

Cylinder #4 is misfiring in an engine with 4 or more cylinders. Engines have a firing order that is used to number the cylinders and it depends upon the engine which one is #4.
If you have a "check engine" light on, start with having the codes read. A misfire code can tell you which cylinder or cylinders are having problems. A misfire could be the cause of your engine vibration.

Wheel cylinders are in the rear drum brake between the shoes. The Engine's cylinders are in the engine block, under the cylinder head.
Misfire can be caused by any condition that doesn't allow for full combustion in an engine. You don't specify what engine you have in your Ranger, but look for things common to both cylinders. Are they on the same ignition coil? Are they next to each other on the engine? Causes can be almost anything, from a bad spark plug to a mechanical fault in the engine itself. I cover this information in my upcoming book Automotive Driveablity: A Guide to Engine Performance Diagnosis. Feel free to visit me at www.autoservicetech.com. I also recently wrote an article on misfire diagnosis for MotorAge magazine that will be listed on my home site soon.
The fuel in the cylinders exploding
I'm not a mechanic / technician but I BELIEVE if the fuel injector is restricted so that the proper air - fuel mixture is not getting to an engine cylinder , that an engine cylinder misfire can occur ( that is only one of the causes of an engine cylinder misfire )
A misfire is when one of the cylinders is accelerating without actually doing anything, it's just a dead-cylinder. In order to fix this you need to tighten the cylinder or adjust the engine connector.
If the check engine light is flashing that means an engine cylinder misfire has been detected
The year, make and engine info would help us help you.
A cylinder misfire happens when one or more of your 6 cylinders of your V6 eninge does not fire properly due to lack of fuel, spark or compression. The more cylinders that are not fireing the more violent the shake will be. If enough cylinders are not firing the car will not run. When you have a misfire with this vehicle your check engine light will flash. The engine light, oil light etc... are known as idiot lights. You ask what this means? IT MEANS YOUR VEHICLE NEEDS SERVICING UNLESS YOU WANT A BLOWN ENGINE!!!
