Toyota Aygo
Simple petrol diagnosis: misfires, vacuum leaks and small-engine lean codes.
What to expect
- Small engines exaggerate unmetered air issues — check for vacuum leaks early.
- Misfires are commonly ignition-related; confirm plug spec and coil behaviour under load.
- Trims that climb at idle usually point to unmetered air rather than fuel delivery.

Tip: Include make/model/year/engine and what changed recently (battery, service, fuel, long idle, short trips). That’s where the diagnosis lives.
Trust note: These profiles are designed to narrow possibilities. Confirm with test data (trims, misfire counters, pressure/smoke tests, voltage checks) before buying parts.
