Dave was on time and called to provide ETA before arrival. He diagnosed my engine vibration to a ignition coil and also low on oil. It's funny that he has to book himself via the app for the parts replacement to work within yourmechanic system. Picked up a new ignition coil and fixed my car on the same day and even went a step further to pick up a quart or oil and top off my low oil.

Kyle was professional and quick, and I appreciated the information he provided on the issue with my car. Although he did call to let me know his previous appointment ran late, he stated his ETA would be 20 minutes but ended up being an hour. My 10:00 appointment time ended up starting well after 11.

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.
