A trouble code only tells you which circuit reported a fault, not which part failed — we test the circuit at your address and tell you what actually broke before you buy anything.
At a glance
- Full scan plus live-data testing at your location
- The failed part shown to you and explained in plain English
- Repair priorities separated into urgent and can-wait
- Diagnostic fee quoted before we drive out
The free code read at a parts counter is a starting point, not a diagnosis. A lean code can come from a cracked vacuum line, a dirty mass airflow sensor, a tired fuel pump, or a lazy oxygen sensor — four different repairs at four very different prices. Replacing whatever part the code happens to mention is how drivers spend hundreds and still see the light come back on a week later.
We pull stored and pending codes, read live data and freeze-frame, and run the physical tests that separate cause from symptom. Then you get a plain-English explanation of what failed, what it costs to fix, and whether the car is safe to drive in the meantime. If you want the repair done, we can usually do it on the spot.
