David was on time, extremely professional and polite. The service (brake pads changed) I had scheduled was more than I needed and David saw to it that I was only charged for the work he performed; I was quoted to have all the pads changed but only need the back set done. Definitely happy with the service he provided and will certainly use this service again for my future car needs. It was refreshing to deal with a mechanic that wasn't out to take my money for services I really didn't need; this was the first time i didn't feel taken advantage of when it came to servicing my car.

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.
