Spark Plug Replacement
Gas Engine Repair — Cheyenne, WY
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. Replacing them on schedule is cheap; ignoring them long enough to damage coils or foul the catalytic converter is not.
TDC installs the correct plug for your engine — not the 'premium' upsell, the right one — gapped and torqued properly. On engines where plug jobs are notorious (tight V6 back banks, aluminum heads with seized plugs), it's worth having someone do it who's been there before.
What's Included
- The correct plug spec for your engine
- Proper gapping and torque — no stripped heads
- Coil boot and wire inspection while in there
- Difficult plug jobs welcome
- Honest advice on real replacement intervals
Straightforward Gas Engine Work
- 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.'
