I sure wish I had found the YOUR MECHANIC site two months ago. I know that I would have saved quite a lot of money using your services on my vehicles. Jose was EXCEPTIONAL in ALL aspects and got the job completed in the estimated time, even though the original Harmonic Balancer was quite difficult to remove from my Van. He also checked numerous things about my van to make sure all was okay and that impressed me. Thank you, Jose. I have already recommended you and YOUR MECHANIC to several friends and family.

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.
