Engine diagnostics
that find the real fault
Check-engine lights, rough running, mystery noises. Proper diagnosis with factory-level tooling in Wilson WA. A written report and a firm repair price, not guesswork.
The part you pay for is the answer
Most expensive engine repairs start as a $60 sensor that nobody bothered to test. Our diagnostic session reads codes, logs live data, checks compression and fuel trims. Then a human interprets it, because a scan tool only tells you where to look.
You get the findings in writing: what's faulty, what it means, what it'll cost to fix and what happens if you leave it. If you take the repair with us, the $165 comes off the bill.
Diagnostics and common engine work
The diag session is a flat fee. Repair prices below are the jobs we quote most often after one.
Engine jobs vary more than most. The diag exists so you pay for one repair, not a pile of maybes.
Warning light guessing game?
A dash light shouldn't be a lucky dip. The $165 diagnosis names the real fault, and it comes off the repair if you fix it here.
Findings and the firm price land in writing first, what you approve is what you pay.
How a diagnosis runs here
We hear your version first
When it happens, hot or cold, what the dash said: the symptom timeline narrows the search fast.
Scan the whole car
Every module, not just the engine ECU. Plenty of 'engine' faults live in the transmission or ABS modules.
Live data and physical tests
Fuel trims, misfire counters, compression, smoke test for vacuum leaks: whatever the clues point to.
Written report + firm price
What's faulty, why, what it costs, what happens if you wait. Emailed same day.
Fix it, verify it
Repair done, codes cleared, live data re-checked on a road test. We prove it's fixed, not just hope.

Diagnoses from the bay
Sofia finds the faults other shops give up on
Sofia's spent 11 years in diagnostics and auto-electrical. She's the tech dealers call when their own scan tool runs out of ideas. Wiring faults, CAN bus weirdness, intermittent anything: that's her home turf.
Her rule is simple: no part gets replaced until it's been proven faulty. Customers see the test results, which is why our comeback rate sits at 0.2%.
- Every module scanned, not just the engine ECU.
- Written report with a firm repair price, emailed the same day.
