Check Engine Light Diagnostics in Atlanta, GA
A check engine light can mean a loose gas cap or a failing catalytic converter — and a lot in between. Big Tee Auto Repair reads the codes and then actually tests to find the real cause anywhere in Metro Atlanta, so you don’t throw money at the wrong part.
Steady light means “get it checked soon.” Flashing light means “stop driving and get it looked at.” Either way, Big Tee diagnoses first and quotes before any repair.
