Dave is the man you can trust! Replaced my front brake pads and rotors in about half hour. When I ask him about the problem with my HID headlights, he is so nice to guide me to buy bulbs from amazon and when delivered I can schedule with him to come and replace the bulbs. A nice thing with YourMechanic is that, you will automatically get assigned with the same mechanic when you schedule services again with them, because you've built connection with your mechanic, assuming the connection is good:) It is so great to have Dave as our mechanic.

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.
