Engine Diagnostics

A check-engine light is a symptom, not a diagnosis. We find the actual fault before we quote the fix - so you never pay to replace parts that weren't the problem.

What we diagnose

  • Check-engine, ABS and airbag warning lights
  • Rough idle, misfires, stalling and hard starts
  • Poor fuel economy and loss of power
  • Overheating and cooling system faults
  • Noises, vibrations and smells you can't place
  • Intermittent faults that never happen at the shop - until we catch them

Diagnosis before parts, always

Parts-swapping is the most expensive way to fix a car. A code tells us which system complained - not which part failed. We test the circuit, the sensor and the mechanical side before anything gets ordered, and we show you what we found in plain language.

You approve the repair with a written estimate in hand. If it's not worth fixing, we'll say that too.

Common questions

What does a diagnostic cost?

A flat diagnostic fee, quoted up front - and if you have us do the repair, we put that fee toward the job.

Can you just read the code for free?

Reading a code takes seconds; knowing what it means takes testing. We'll always tell you the code, but a real diagnosis is what saves you money.

My light went off - am I fine?

The fault is still stored. If it set once it will usually set again, and it's cheaper to catch early.

Stop guessing what that light means.
