Diagnostics & service
A code tells us where to look. Testing tells us what's wrong.
Free code reads at parts stores are useful, but a code like P0301 means “cylinder 1 misfire”, not “replace the spark plug.” Here is what a proper diagnosis involves.
- 1
Interview
When does it happen? Cold, hot, at speed, after rain? Your answers narrow it faster than any scanner.
- 2
Scan and freeze-frame
Stored codes plus the engine conditions at the moment each one set.
- 3
Live data
Fuel trims, sensor readings and misfire counters while the engine runs.
- 4
Pinpoint tests
Swap a coil, measure a circuit, smoke-test for vacuum leaks. Prove the cause.
- 5
Report and quote
What failed, how we know, and what it costs to fix. Then you decide.
Maintenance by the book, your book.
We follow the maintenance schedule in your owner's manual, by mileage and age. If the shop down the road is recommending a flush that isn't in your schedule, bring the quote. We'll tell you honestly.
