Mr. Phan was early to his appointment and fixed front and back brakes while my car was parked at work in about an hour. He was very polite and professional and now my brakes do not squeek when I apply pressure. He was so honest he told me my back brakes did not need to be replaced but I told him to do it anyways because I thought it was a good idea since I have never replaced them since I have owned my car. This is my second time using mobile mechanic and I am very pleased with the pricing structure and level of professionalism. I would definalty reccomend this service to my friends and family.

Lucas

I had an electrical problem with my car (wouldn't start). I thought it went beyond the typical dead battery situation (battery wouldn't take a jump, there were no preceeding hard starts), so I wanted everything tested. It was convenient to have him come to the car, instead of me taking the car to a shop (since it wouldn't start, we were probably looking at towing). I could have changed the battery out myself, but I wouldn't have known if there was some underlying issue or not (starter, generator, alternator). It turned out that it just was the battery (battery was bad, needed to be replaced), although Lucas tested everything, so now I have some peace of mind that it's not going to happen again.

All about Spark Plug Replacement

The spark plugs are an important part of the ignition system. When you turn the ignition key (car's key) on, it causes the ignition coil to generate the spark which ignites the air-fuel mixture in the engine cylinders to start the engine. The number of spark plugs in the car is the same as the number of cylinders, although some vehicle manufacturers will use two spark plugs per cylinder. Over time, the spark plugs wear out and require replacement. When the spark plugs wear out, it is harder for it the air-fuel mixture to ignite, resulting in engine misfires. If one of the spark plugs has failed, the car will still start and run, but it will run poorly. On some vehicles, spark plug replacement may be labor intensive and involve removal of the intake plenum.
