Theodore

Theodore was a great help. He was able to diagnose my issue within 20 minutes. Unfortunately, the issue was not something that he could resolve, as it ended up being an issue with the tire itself. He recommended that I go back to the shop where I purchased my tires to have the issue resolved. He's very friendly and professional.

David

I thought David was great. He was very courteous and professional. He did a pre-used car inspection for me on May 7, 2016. However, I filled the vehicle with gas yesterday and it has serious gas leak. So this is an aspect of his inspection that he missed. Again, I thought he was very professional and would recommend him. But any such inspections in the future should include the gas tank.

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.
