I sure wish I had found the YOUR MECHANIC site two months ago. I know that I would have saved quite a lot of money using your services on my vehicles. Jose was EXCEPTIONAL in ALL aspects and got the job completed in the estimated time, even though the original Harmonic Balancer was quite difficult to remove from my Van. He also checked numerous things about my van to make sure all was okay and that impressed me. Thank you, Jose. I have already recommended you and YOUR MECHANIC to several friends and family.

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.
