Alex replaced power window regulators for both front doors and did a pretty decent job. He even inspected the car and found that front brake pads and Rotor needs to be replaced and helped me in getting quote for that. I have scheduled another appointment with him to replace front brakes. Overall, I have been very satisfied with the services provided by Alex.

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.
