GM Diagnostic Services in Houston, TX
Diagnostic work is some of the most demanding work in this industry and it's where 25 years of experience makes the biggest difference. We've seen every fault code, every intermittent issue, and every problem that only shows up on a test drive at operating temperature. We don't guess, because there's a good chance we've seen it before.
Skip the headaches and guessing games. Let us diagnose and fix it right the first time.
Why Bring Your GM to Us for Diagnostics
We specialize exclusively in GM. That means when your C7 throws a knock sensor code and you've already changed the knock sensor but the problem didn't go away. Or your truck has a misfire code even after changing the spark plugs and wires. Or your CTS-V has a drivability issue three other shops couldn't figure out. We've got you covered.
GM specific experience isn't just a marketing claim for us. It's the reason customers drive past other shops to get here.
Diagnostics at Houston House of Power
We regularly take in vehicles that have been through other shops without a resolution. Misfire complaints, drivability issues, tune related problems, oil consumption, valvetrain noise. We diagnose methodically and we communicate what we find before we start any sort of repair. There's a reason people compliment our communication process. We aren't your normal speed shop.
Examples of typical diagnostic and repair services we handle:
Check engine light diagnosis and repair, drivability and performance complaints, knock and misfire diagnosis, electrical diagnosis and repair, AFM/DOD lifter failure on LS and LT cars and trucks, post build inspection and startup, tune audits and corrections, overheating and cooling system diagnosis, oil consumption and valvetrain diagnosis.
If you have a problem, we'd love to fix it for you!
Diagnostic Pricing
Diagnostic time is billed at our standard shop rate. If the repair is authorized and completed with us, diagnostic fees are typically applied toward the repair cost. Call us and we'll give you a straight answer on what to expect before you bring the car in.
