Normally I do not confess to auto techs that I spent 40 years as a GM Service Manager and Service Advisor. BUT, Brikk was so pleasant and likable, our conversation was that of cars. He not only fixed my problem, but was sure to check other items on my car that I had not complained about. As I always tell everyone, there is but one thing that surpasses great customer service, and that is MORE of it...Thank you Brikk for a job well done, and if I ever need your service again, consider your phone ringing...Thanks

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.
