Jason went far and beyond what I could have expected! Do to an incorrectly assigned time for completion in the job I needed done, Jason did far more work then he knew was coming. I needed my PCV hose changed, and low and behold, my Mazda required the removal of the headers to get to the PCV hose. Without question, Jason handled his business and got it done. On top of that, he replaced my brake discs and pads, and on a request after he arrived, he went to the auto parts store and bought and replaced one of my headlights for me. Jason ended up working for 8 hours to get the job done. Then, after there was an issue with my power steering making noise after he worked on the car, he responded quickly and came out to my work to figure out and fix the issue. Jason did a great job, and I definitely recommend him to anyone needing work done. He will go above and beyond.

Having the 1st mechanic stand me up I was apprehensive on the outcome of the second scheduled apt. I've had my faith restored in this program thanks to Isai who showed up early ready to do the job which was done in my driveway for over have the price quoted from pep boys and the convenience is what sold me also. He discovered that the original bid from pep boys stated I needed 4 motor mounts and Isai was forthright telling me only two needed to be replaced. An honest mechanic is a rare commodity these days so Isai is who I will be requesting from here on out for all my vehicles needs.

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.
