Jeff my mechanic was fantastic and the car is running very well now. The yourmechanic.com service was a bit suspect. Not sure they have all the website/customer service kinks worked out yet but, Jeff overcame the obstacles quickly and with a great attitude. The website service did not understand what parts I needed (and its simple really, as it was just motor mounts). I suspected this and called to confirm and was told they would make sure the mechanic would have what he needed. He did not, it delayed the repair time and changed the price.

This was my first time using a at home service for my car , after reading the comments from other customers I decided to give it a try , and oh my gosh I was totally shocked by the professionalism that Rodney provided he showed up early which I was fine with cause I am a tickler for being on time and on time he was , so that was a big check mark , professionally dressed with company logo uniform . Not only did he find out the problem with my car but also did a inspection of the entire car , let me know that my tires were low and recommended that as soon as i get it running go and get them inflated and told me what pressure for front and the rear . So yes I was very happy with Rodney and the service he provided and the overall attention of the company putting customers first . Looking forward to seeing Rodney next week for the repairs .

All about Ignition Coil Replacement

Ignition coils transform low voltage electrical power 12 volts D.C. to high voltage current 50,000 volts D.C. or higher. The spark generated by the ignition coil ignites the fuel and air mixture in the engine that enables the car to start and run smoothly. If an ignition coil is not working properly, no spark will ignite the air fuel mixture, causing a misfire. A bad ignition coil can severely damage the engine or catalytic converter. If your car is equipped with “coil over plugs,” then it is recommended that you replace the spark plugs. If your car uses a single coil for the ignition system, it is not necessary to change the spark plugs.
