Theodore was fantastic. He was very aware that we still had a business to run while he was working on our vehicle.

Casey changed valve cover gaskets on my 2001 Subaru six cylinder engine. A very time consuming job. He arrived promptly and worked diligently to get the job done. I recommend him for any work that is needed to be done. My job was something I did not want to do myself and Casey performed better than I could have expected. Will use him again if the need arises.

Number #1 just knowing that you as a business were on the internet surprised me totally. I am a disabled 74 year old woman that doesn't get out much and when my fan belts broke I didn't know where to turn. Then here comes this big kid driving slowly down my driveway being careful not to hit my little dogs, he gets out of the car and says "Mary Brooks" and I said "Brandon", he then said lets fix your car....What a pleasant gentle young man, described to me what he was going to do after looking at the problem. After fixing the problem he went on to say the things that I should be concerned and how to fix them or to give Your Mechanic a call and have them come out again to possibly fix whatever needed to be done and of course I would ask for him, Brandon. I will use your service and Brandon again. Thank you so very much. Give Brandon Kudos for a job well done. Mary E Brooks

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.
