Can Bad Spark Plugs Cause Misfire
New spark plugs should make your car run better, but sometimes, it causes misfires. Faulty spark plugs can indeed cause misfires. Spark plugs ignite the fuel in your engine. If they are bad, they can’t do this job well. Misfires happen because the spark is not strong enough to burn the fuel.
This makes the engine run rough and can cause a loss of power. Misfires may also trigger the check engine light. Bad spark plugs can also make your car hard to start or cause it to stall. If you notice these issues after changing spark plugs, they might be the cause.
Can Spark Plug Gap Cause Misfire
A misfire can be caused by several factors, and one common reason is the spark plug gap. The gap is the space between the center and ground electrode of the spark plug. If this gap is not set correctly, it can lead to weak sparks, which might not ignite the fuel properly.
This improper ignition can cause the engine to misfire. Sometimes, the gap might be too wide or too narrow, which can happen if the spark plugs are not pre-gapped or if they get damaged during installation. Checking and adjusting the spark plug gap can often solve the misfire issue.
It is important to use a feeler gauge to measure the gap accurately and make necessary adjustments as per your car’s specifications.
