Honorio
14 years of experience
Honorio diagnosed and fixed my power window + outlets despite one of the parts I ordered being defective. He took the extra time to explain to me what the problems were and how he was going about fixing them. In the end, the entire job took longer than expected but he honored his original labor quote. I couldn't be more satisfied with the job he did.

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.
