Zachary is an excellent mechanic! He arrived a little early for our appointment. He carefully evaluated and diagnosed the problems with my GMC Envoy overheating - It needs a new serpentine belt and drive belt tensioner. We had two previous mechanics who could not figure this out, so we really appreciate Zachary. He answered all our questions completely and made sure we understood everything. We're looking forward to working with Zachary again, and highly recommend him to everyone!

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.
