Godwin did a great job changing the oil in my car. First, he called me and arrived early for the appointment which I really appreciated. Then he answered my questions about the car that were not even related to the oil change. He has a good attitude and you can tell he know what he is doing. I absolutely liked the way he did the job and will certainly use his services 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.
