Theodore

Theo was ontime and extremely courteous. He diagnosed my vintage Mercedes' problem and returned a week later. The replacement part they sent him was incorrect, so he reassembled my dashboard and waited for the correct replacement. When it arrived, he not only installed it, but followed me to a service station and then test drove the vehicle to check for other problems. I will ABSOLUTELY use Your Mechanic.com in the future to avail myself of a great mobile service. Thank you.

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.
