Check engine light glaring at you? Let's pull the codes and get to the truth.

Codes Are A Starting Point
We use codes to guide testing, not as a parts list.
You Approve First
We show you what's going on and the exact price before work starts.
Why It Matters
Do Not Guess At A Check Engine Light.
A trouble code points to a system, not the specific part that failed. Whether it's a misfire, a sensor fault, or an emissions issue, we use the codes to guide our testing, not as a parts shopping list. We find the actual cause and send a clear plan before repairs begin.
A trouble code often names a system, not the failed part. Replacing parts based on a code alone can waste money.
We find the cause. You see the estimate. You decide what's next.

FAQ
Check Engine Light Questions.
What will this cost?
You'll know the price before anything happens. If testing is needed to find the cause, we tell you that cost up front (deep diagnostics start at $125), and you approve the full repair price before any work begins. Saying no is always fine.
How fast can you get me in?
Grab the next open drop-off window when you book, or use the after-hours key box tonight and we'll get eyes on it in the morning. In a hurry? Text us and we'll tell you straight what's possible.
Can I drive with the check engine light on?
Sometimes, but a flashing check engine light is more serious. If your car is shaking, losing power, or the light is flashing, avoid driving and schedule service.
Can you just clear the code?
Clearing a code does not fix the cause. We diagnose the reason the light came on.
Is diagnosis more than scanning codes?
Yes. Codes are only the starting point. Testing confirms the repair.
Will you explain the code?
Yes. We explain what the code means and what testing found.
