Steven

After moving to a new city I needed a new mechanic. I was set up with Steven who came to a dealership to meet me and inspect a used Mercades I was interested in. He was very genuine about his review of the car along with being highly experienced. It seemed like he truly cared about me and my purchase unlike past experiences. Steven was just an overall nice guy who I knew I could trust off the bat and I will continue to use him from YourMechanic in the future. Thanks for making this completely hassle free and providing a great report of my new cars health.

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.
