Gas Engine Repair in Cheyenne, Wyoming
Honesty & Quality
Diesel may be in the name, but TDC Automotive works on gas vehicles every day — cars, SUVs, vans and half-ton pickups from every major manufacturer. Misfires, oil changes, spark plugs, filters, leaks: the everyday work that keeps a family's vehicles on the road, done by a mechanic who treats a Camry with the same care as a Cummins.
Gas work is billed at $125/hr, diagnosis follows the same verify-inspect-scan-test procedure as everything else in the shop, and you'll get a straight answer about what your vehicle needs now versus what can wait. Honesty & Quality isn't just the tagline on the logo.
Gas Engine Repair Services
Misfire Diagnostics
A misfire — the stumble, shake, or flashing check engine light that means a cylinder isn't pulling its weight — has three possible causes: spark, fuel, or mechanical.

An oil change at TDC gets you the correct-specification oil for your engine, a quality filter, and something a quick-lube can't offer: a working mechanic's eyes on your vehicle while it's up in the air.
Learn more →Spark Plug Replacement
Spark plugs are a wear item with a real service life — and when they're past it, you feel it as rough idle, hesitation, harder cold starts and worse fuel mileage.
Learn more →Engine Air Filter
Between prairie wind, gravel roads and construction dust, air filters around Cheyenne work harder than most.

- Listen first
You know your vehicle. The diagnosis starts with what you've noticed — sounds, smells, when it happens.
- Diagnose by procedure
Verify the complaint, inspect the vehicle, scan for codes, test to confirm the failing part.
- Quote before work
You get the findings and the price before the repair starts. No surprise line items.
- Fix what's broken
Repairs use quality parts, and what doesn't need fixing doesn't get 'recommended.'
