Check Engine Light

  • Replacing the Engine Mounts on Your Fleet

    Commercial trucks have heavy engines, and they spend a lot of time running, particularly at idle. As a result, the mounts that secure the engine to chassis of the truck have a tendency to wear out, causing all sorts of shaking and vibration that the driver will feel in the cab of the truck. At Repair Masters Automotive LLC in Boulder & Louisville, we can take care of that for you.

  • Sometimes it is obvious, others we have to hunt for it!

    Here at Repair Masters Automotive LLC in Boulder & Louisville we often do diagnostics and sometimes the problem is obvious after hooking the car up to the computer and reading the codes.  However, sometimes it isn't obvious during a test drive or after hooking it up to all those computer programs!  You know there is a problem and a Check Engine Light is on with the fleet customer telling you the car has been having issues starting and the light has been going off and on depending on several factors.  No pattern, no simple answer but the problem becomes obvious when you start following the "threads of the issue" thanks to all that ASE Technician training.
