Jeffrey arrived on time, maybe even a little early! He got right to the problem of the car not starting and got it started without a problem (we tried unsuccessfully to jump start it before setting the appointment). Jeffrey was very helpful and we already have another appointment set to get a new battery in one car and to have the oil changed in our other one. Our first experience with YourMechanic and Jeffrey was excellent.

Isai was simply but amazing! Autozone had told me I needed to replace my alternator after jumping it that morning and when I booked Isai to do the replacement worked, he quickly noticed that I did not have an alternator issue! He stayed with me for another 45 minutes explaining everything and teaching me the basics for any other issues, if my car went out again! I will be recommending this place to friends and family members!

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.
