All manufacturers use their own method of numbering cylinders, so check the manufacturer’s website for more information. If you have a “V” engine, do some research to find a diagram of the engine cylinders. If you have an inline engine, number 1 cylinder would be closest to the belts. Different engine types have the cylinders arranged in different positions. Multiple cylinders are commonly arranged side by side in an engine block. Based on the type of engine your vehicle has, you can identify the specific cylinder or cylinders that are not firing.Ī cylinder is the central part of a reciprocating engine or pump, and is the space in which a piston travels. Step 3: Identify the cylinders on your engine. There may be other DTCs such as coil codes or fuel pressure codes related to fuel, spark, or compression that can help you diagnose the problem. Pay attention to all ignition coil primary circuit codes. For example: P0300 refers to a random misfire, P0304 refers to a misfire occurring in cylinder 4, while P0301 signifies cylinder 1 and so on. “X” refers to the cylinder in which the misfire occurred. “P” refers to Powertrain while 030x refers to a detected misfire. Misfire codes are universal and go from P0300 to p03xx. The DTC numbers show specific circumstances where the collected data does not meet acceptable values.

Step 2: Get a printout with all the code numbers. If you do not have access to a scan tool, your local parts store can scan your car for free. Use a scan tool to find the diagnostic trouble code (DTC) numbers for the problem. Step 1: Scan the car to find the misfiring cylinders. Part 1 of 4: Locate the misfiring cylinder(s) Sometimes, misfiring may not be caused by a total loss of spark but by incorrect sparking or by high-voltage electrical leaks.

This includes worn, fouled or damaged spark plugs, bad plug wires or a cracked distributor cap. Loss of spark is caused by anything that prevents coil voltage from jumping the electrode gap at the end of the spark plug. This article focusses on finding the source of misfires caused by the loss of spark. Misfiring can be caused by loss of spark imbalanced air/fuel mixture or loss of compression.
The most common cause for a misfire is a problem related to the ignition system. The check engine light may come on or keep flashing.
The engine may be running poorly and one or more cylinders may be misfiring. While idling, the engine may shake so badly that vibrations can be felt throughout the vehicle. An engine misfire is accompanied by a loss of power directly proportional to the severity of the misfire. When an engine misfires, one or more cylinders fail to fire properly, either because of ignition or fuel-related issues. Misfiring is a common drivability problem that may take some time to diagnose, depending on the cause.
