Why bring it here
Not the cheapest. The straightest.
Manufacturer-specific scan tools, not just generic OBD-II readers
We don't guess — we test. Sensor data, fuel trims, freeze-frame analysis
Diagnostic fee credited toward repair if you have us fix it
“Quickly diagnosed and repaired my vehicle for a very reasonable price. They aired my tires up without me asking. That may not be a big deal to some, but it meant a lot to me and demonstrated their concern for details.”
Common questions
Engine Diagnostics FAQ.
Will free code-reading at a parts store tell me what's wrong?
It tells you a code, not a diagnosis. A P0420 code, for example, can be a catalytic converter, an O2 sensor, an exhaust leak, or a fuel-mixture problem. Real diagnostics rule out the cheap fixes before recommending the expensive ones.
Why does diagnostics cost money?
Real diagnosis takes time, manufacturer-specific tools, and decades of experience. We credit the diagnostic fee toward the repair if you authorize the work — so when we find it, you only pay once.
My check engine light is flashing — should I keep driving?
No. A flashing CEL means an active misfire that can damage the catalytic converter. Pull over, get it towed, and call us at (972) 231-2886.
Can you help if I failed Texas state inspection?
Yes — emissions diagnostics is one of our specialties. Bring the failure paperwork, we'll diagnose, repair, and re-test.
