A+ quality work, professionalism and friendliness. Enrique performed an initial inspection on my vehicle due to the temperature gauge light coming on. He arrived early and upon completion of the inspection provided me with very detailed information regarding the issue reported. I scheduled an appointment to perform the recommended work and let me just say Enrique is a jewel. Again, he arrived early he was friendly and courteous and described everything to me in detail. As soon as he completed the job, he explained what he did, why he did not have to perform certain other recommended repairs and the information was provided in such a way, that even me as a woman who knows nothing about cars could understand. I will definitely use Enrique in the future :-)

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.
