When I have time, I like to work on my car. I generally know how long things should take. More often than not, when I go to a traditional shop, the quotes are very high and come with recommendations for services that I know are not necessary. Thank you for providing a great service, a reasonable price, and honest recommendations. Also, thank you for taking care of your mechanics. It is nice to see people like Jesus that love the work they do and like the company for which they work!

Norman arrived in a timely manner and was very thorough in his diagnosis. It only took minutes before finding the cause of the coolant leak. More time was spent on other inspections and recommended services. His overall expertise and professionalism was very much appreciated. Went above and beyond expectations. Booking the repair as we speak. Will be advertising Norman as a preferred mechanic a monster friends and peers.

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.
