Engine Diagnostics Near Me

Vehicles are equipped with sophisticated computer systems that monitor engine performance, emissions, and other key parameters. When a failing sensor, clogged fuel injector, or misfire happens, the onboard computer stores a code and may trigger the check engine light.


Using advanced diagnostic tools and scanners, our technicians connect to your vehicle’s computer system to retrieve the codes and interpret their meaning. From there, we utilize our experience and additional testing to pinpoint the root cause of the issue.


The most common issues that may require diagnostics include:


  1. Check engine light on or flashing
  2. Decreased fuel efficiency
  3. Engine misfiring or stalling
  4. Rough idling
  5. Difficulty starting
  6. Poor acceleration or performance


At Noller Fleet & Auto Center, we dig deeper. We have the tools, training, and technology to diagnose and fix the issue the first time properly. Our skilled technicians are experienced in working with all makes and models.


If your check engine light is on, don’t ignore it. Driving with an active engine warning can cause more damage or even leave you stranded. A quick visit to Noller Fleet & Auto Center can help you avoid bigger problems (and repair bills) down the road.
