Honorios was excellent. He arrived on time, and patiently worked for a few hours and all the things - changing brakes, replacing bulbs. He explained the work he did and showed how my car is different from other models. He also educated me to watch for potential repairs in the future. I would trust Honorios with any car service I have and look forward to hiring him again.

All about Ignition Cable (Spark plug wires) Replacement

The ignition cables, also known as “spark plug wires” are part of the ignition system. They transfer the spark from the distributor or ignition coil to spark plugs that ignite the air-fuel mixture, starting the engine. Over time, the cables can get weak and break down. This will make it harder for the spark to reach the engine cylinders, resulting in engine misfires. The car may not start at all. If one of the spark plugs has gone bad, the car will still start and run, but it will run poorly.
