I thought David's service was A1. I am an out of state client & hired the mechanic to do an on site pre-purchase inspection for a vehicle I was to bid on the next day. David was courteous when he called to confirm w/ me. He actually went to the job site early. He appeared to be as thorough as possible given that he could not lift the vehicle in the air. His notes & pics were detailed. He explained the issues he noted as well as the bright spots regarding the vehicle. Along w/ the verbal dictated notes he left in my inspection...I was able to talk to the mechanic personally & get a lil further info. I was very appreciative of David && his work. He helped me in making a costly buying decision. Thanks again David. I would certainly recommend the service & use it again.

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.
