FAQs
How Do I Know If My Truck Needs Diagnostic Testing?
If you see warning lights, experience poor fuel efficiency, notice slow starts, or hear unusual noises, a diagnostic test is essential. Modern trucks store error codes that can only be read and interpreted by specialized equipment. A scan ensures we fix the right problem the first time.
Can Electrical Issues Affect Engine Performance?
Yes. The ECM, sensors, and wiring all play a critical role in fuel injection, timing, and emissions systems. If any component is failing, you may notice symptoms such as misfires, hard starts, or reduced power.
