Why Harmony drivers book mobile tune-up & spark plug replacement
Harmony is small-town Iredell, and the nearest full-service shop is a real drive. Bringing the mechanic to you makes more sense out here than almost anywhere. For tune-up & spark plug replacement, that means no tow, no ride-share to a shop, and no day off work — we do the job on site and you get your keys back the same visit.
What's included
Modern engines don't need a tune-up every 12,000 miles like they used to, but when the plugs are worn the car misfires, idles rough, and drinks fuel. A proper tune-up replaces spark plugs at the right gap and torque, tests the coils, and cleans the throttle body so the engine breathes like it should.
- Scan for misfire history and identify weak cylinders
- Remove coils and old plugs, inspect for oil, fouling, or heat damage
- Install correct iridium or platinum plugs, gapped and torqued
- Replace any failing ignition coils or boots
- Clean the throttle body and replace the engine air filter
- Clear codes and road-test
Signs it's time
- Rough idle or shaking at stoplights
- Hesitation when you accelerate
- Check engine light with a misfire code (P0300–P0308)
- Fuel economy has dropped
- Hard starting
Scheduling in Harmony
We do plugs on most engines in a driveway. A few V6 minivans and some turbo engines with intake manifolds in the way take longer, and we'll tell you up front if yours is one of them. We cover all of Harmony, including ZIP code 28634, with no travel surcharge.
