Russell

Russell went out of his way to assist me with my car when it wouldn't start for me. He called to confirm our appointment and to ask if he could come early. When my car started right away, he still gave me a jump to gauge the battery power level and suggested I bring my car back to the dealer for further servicing since it was still under warranty. Didn't try to pressure me into anything I didn't need. Great service.

Jose provided exception service. He was very knowledgeable and knew how to diagnose my car problem quickly and gave me plenty of good car maintenance tips. He took his time and did a quality job. I was a little skeptical using yourmechanic.com for the first time but I will definitely be using it more often given how positive my first experience was.

Enrique

Excellent. Rick showed up early and was very friendly and courteous. He was not aggressive in upselling me on additional services which is important to me. He only made recommendations which were actually crucial. He set an appointment for me but told me it was optional and that I could cancel, which I did due to financial restraints at the moment, but I will be booking with him in the near future for the recommended services.

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.
