ENGINE DIAGNOSTICS IN LEXINGTON, TN
DON'T GUESS. DIAGNOSE THE PROBLEM.
DON'T GUESS. DIAGNOSE THE PROBLEM.
Warning lights, poor performance, unusual noises, rough running, loss of power, and starting problems can have multiple causes. A trouble code points to a circuit where the computer saw an anomaly—it does not automatically identify which part to replace. At A1 Auto, we find out what is actually wrong before recommending any repair.
What's included
- Check engine light scanning & advanced computer code analysis
- Live data stream monitoring & sensor verification (O2, MAF, MAP, TPS)
- Misfire analysis, cylinder compression & ignition coil testing
- Fuel pressure, injector balance & vacuum leak diagnosis
- Intermittent drivability, stall, & rough idle troubleshooting
- Transparent recommendations before any replacement parts are ordered
