Check engine light diagnosis in Detroit.
A check engine light can mean anything from a loose gas cap to a failing sensor or a misfire. A mechanic reads the codes, at a shop near you or where the car is parked, and tells you what's actually wrong and what it costs to fix before any work starts.
Signs you need check engine light diagnosis
The light is on and steady
Something needs attention soon. Get it checked before it gets worse.

Usually a misfire. Pull over when it is safe and stop driving if you can.

A bad oxygen sensor or misfire often shows up at the pump first.
Rough idle or hesitation
Shaking at a stoplight or stumbling when you press the gas.
