Drivability Problems
If any of these sound familiar, the engine is talking. We translate.
Usually a bad coil, plug, injector, or compression issue. We pull codes and test cylinders to confirm.
Vacuum leak, dirty throttle body, failing sensor, or misfire. Often a fast fix once we identify it.
Could be ignition, fuel, exhaust, or sensor-related. We diagnose live data and pinpoint the issue.
Often O2 sensor, MAF sensor, dragging brakes, or a misfire. We check what's actually affecting it.
Thermostat, water pump, radiator, or fan issue. We diagnose cooling on-site.
We pull the code, but more importantly — we test the circuit. The code points; it doesn't always answer.
A code reader points at a problem. It doesn't always answer one. P0420 isn't always a catalytic converter. P0300 isn't always plugs. We test the system before we replace anything.
