Wait until it is dark, turn off the headlights and check under the hood. An old trick that you can do to check them is to make sure that they are not bleeding spark. If the plugs look fine, check the spark plug wires (if so equipped), make sure that they look good (not dry rotted, not melted). The spark plug to the left was bad enough to cause a bad backfire and threw the P0301 trouble code, which indicated cylinder 1 had the misfire Here’s a more in depth guide on bad spark plugs. They can tell you a lot about what is going on with the engine. If there is reason to believe that the ignition system has gone bad, take a look at the spark plugs first. If you do have a problem with the ignition system, you’ll more than likely get a diagnostic trouble code that indicates that there is a problem with the ignition system, such as P0300 (Random Multiple Misfire) or P030X where X represents the exact cylinder that is misfiring. Although with a modern vehicle, it should be able to go near – 100,000 miles without the plugs showing much damage. The spark plugs themselves can go bad over time. The coil or coil packs need to be strong. It relies on data from the crank and cam sensors to time the spark properly. Your ignition system is more than just the spark plugs. Here are the most likely causes of sputtering: This can radically reduce the time it takes you to diagnose the problem.Īny failure in the process listed above can lead to a sputtering engine. It is then expelled through the exhaust, where it is then scrubbed by the catalytic converter before being sent through the exhaust pipe.īefore diving into our list of the most common reasons that a Cherokee’s engine sputters, make sure to check for trouble codes if you have a check engine light on. Once compressed, the mixture it is ignited by the spark plugs. The air is then guided into the cylinder where fuel is added and compressed. It pulls in air (where it is measured by the mass airflow sensor). If your Jeep Cherokee has a sputter, it is most likely going to be caused by bad fuel system, ignition system, MAF sensor, or bad catalytic converter. A sputtering engine can indicate a number of problems.
