Diagnostic fee credited toward repair if you have us fix it

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.
