Robert is great! Knows what he is doing and very professional. Assessed the problem immediately and verified other areas of my car with no BS behind his assessment. I will definitely be recommending Robert and "Your Mechanic" to friends and co-workers. Honest and down-to-earth. Wil

Lucas

Always reluctant to hire a new mechanic - but Lucas was thorough, professional, knowledgeable,helpful, friendly, courteous. He went straight to work, isolated my problems, gave me fair and reasonable quotes. I will keep his card and probably keep him busy. My car was a pass down from my father - 16 years old, 200,000 miles and in need of some TLC. Lucas is my guy! Highly recommended.

Tom

Had an amazing first experience with Tom. I've already told my neighbor, my brother, and my Dad they need to start using him. Did an incredible professional job, even stepped me through the process so I can do it myself next time. It was very reassuring watching Tom work and seeing everything come apart and put back together with the new parts. YourMechanic is the opposite of everything that is wrong with the typical mechanic shop. Car drives perfectly now and buying my own parts and having Tom install them saved me a big chunk of change.

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.
