Lucas

Lucas was excellent. He was knowledgeable friendly; Lucas shared what he was doing to my car and why. I know a lot more about my car as a result of him coming to work on it. My Infiniti was a tall order: Lucas arrived at 11AM and stayed until about 5:30PM to finish. Upon completing the prescribed work, he showed me why a certain (previously insurmountable) issue was occurring, and asked to replace one final part. I said yes, after which Lucas made arrangements to go pick up the necessary part and return (he didn't leave until approximately 8PM). Then, the next day, Lucas contacted me again to let me know that a more updated of the part existed. He asked if we could schedule a time for him to come back and replace the part (ignition coil) one more time. Lucas goes the extra mile.

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.
