Jose

Jose went above and beyond my expectation. We wanted to buy a car out of state and needed an extra set of eyes to confirm that this was the car for us. He listened to my concerns prior to inspecting the car and gave me a very thorough run down of the car after his inspection. The man knows his stuff and did a very thorough job with his inspection.

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.
