Patrick did an amazing job diagnosing my car's A/C system. He was very thorough and actually saved me a bunch of money from the original estimate. He attacked the issue starting with the least expensive option and that allowed him to eliminate some of the expensive portions of the repair. He went above and beyond to help and I will start using Your Mechanic whenever I need a repair. Thank you Patrick you were awesome!

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.
