CAR DIAGNOSTICS THAT FIND THE ACTUAL PROBLEM
A diagnostic code does not always tell you exactly what is wrong with your car. If your check engine light is on, your car is running rough, or you’re experiencing a loss of power, proper vehicle diagnostics can help identify the actual cause of the problem.
Wicked Metalworks uses diagnostic scan tools and hands-on testing to inspect live vehicle data, fault codes, sensors, wiring, fuel delivery, ignition systems, air intake systems, and other components that may be causing the issue.
We don’t simply clear a check engine light or start replacing parts based on a code. Our diagnostic process is designed to determine why the warning light came on or why the vehicle is not running correctly.
From daily drivers to performance and modified vehicles, Wicked Metalworks provides car diagnostics and engine troubleshooting in Appleton, WI and throughout the Fox Valley.
