Working with Brian Z. was a 10 out of 10 experience. It was my first use of YourMechanic.com, and it will not be the last so long as he's on the case. Brian came by on time and quickly changed out both my rear differential and my power steering fluids. Along the way, he accurately noted the other areas where the car needed future maintenance. Brian's love for this work shines through in his professionalism and abundant knowledge, in particular of Nissan products. I will be asking for him from now on for my car repair needs!

All about Spark Plug Replacement

The spark plugs are an important part of the ignition system. When you turn the ignition key (car's key) on, it causes the ignition coil to generate the spark which ignites the air-fuel mixture in the engine cylinders to start the engine. The number of spark plugs in the car is the same as the number of cylinders, although some vehicle manufacturers will use two spark plugs per cylinder. Over time, the spark plugs wear out and require replacement. When the spark plugs wear out, it is harder for it the air-fuel mixture to ignite, resulting in engine misfires. If one of the spark plugs has failed, the car will still start and run, but it will run poorly. On some vehicles, spark plug replacement may be labor intensive and involve removal of the intake plenum.
