A tune-up at Mr Automotive Repair in Gainesville, GA runs between $149 and $399 depending on your vehicle's make, model, and what it actually needs — not a flat rate we pull out of thin air. I've been doing this for 16 years and I'll tell you straight: half the cars that come in here labeled 'needs a tune-up' have one specific issue, and the other half have been running on neglected spark plugs for 40,000 miles past their service interval. We diagnose first, then recommend — so you're not paying for parts your car doesn't need. Every tune-up we perform is backed by our 12-month/12,000-mile warranty, and our ASE Certified technicians are doing the work, not a trainee on their third week.

TL;DR

Tune-ups cost $149–$399 depending on your vehicle's specific needs.
All work is backed by a 12-month/12,000-mile warranty.
We diagnose before we recommend — no unnecessary upsells.

What's Included

Spark plug inspection and replacement using OEM-spec or equivalent plugs (iridium or platinum where required)
Engine air filter inspection and replacement if needed
Fuel system inspection including throttle body and fuel injector condition check
Ignition coil and coil boot inspection for cracks, corrosion, or misfiring
OBD-II diagnostic scan to check for stored or pending trouble codes
Idle speed and throttle response check
PCV valve inspection for proper crankcase ventilation
Visual inspection of belts, hoses, and fluid levels while we're already under the hood

Signs Your Engine Is Overdue for a Tune-Up

⚠ Your check engine light is on and you've noticed a rough or uneven idle
⚠ The engine hesitates, stumbles, or jerks when you accelerate from a stop
⚠ You're filling up at the gas station more often than usual — noticeable drop in fuel economy
⚠ The engine misfires or feels like it's 'missing' especially at highway speeds
⚠ Hard starts — the car cranks longer than it used to before firing up
⚠ You feel vibrations or shaking at idle that weren't there six months ago

Our Tune Up Process

1

First we pull a full OBD-II scan and document any active, pending, or historical fault codes — this tells us if we're dealing with a straightforward maintenance tune-up or something that needs to be addressed before we swap parts.
2

We remove and inspect every spark plug individually, reading the deposit patterns to check combustion health — oil fouling, carbon buildup, or a white/chalky tip each tells a different story about what's happening inside your engine.
3

We inspect the ignition coils and coil-on-plug boots for carbon tracking, cracks, and resistance issues using a multimeter — a bad coil won't be fixed by new plugs, and I'm not going to install fresh plugs into a failing ignition system.
4

We check and replace the engine air filter and PCV valve if they're due, then inspect the throttle body for carbon buildup that can cause rough idle and sluggish throttle response — common on direct-injection engines that see a lot of Gainesville stop-and-go traffic.
5

After reassembly, we road test the vehicle and re-scan for codes to confirm the misfires are resolved and the engine is running cleanly before we hand you the keys — we don't consider the job done until the data confirms it.

Pro Tip

Georgia's humidity and heat cycle are genuinely harder on ignition components than most people realize — coil boots crack faster here than they do in dry climates, and that leads to misfire codes that get misdiagnosed as a fuel problem. If your vehicle uses iridium or platinum spark plugs, don't let anyone talk you into replacing them at 30,000 miles — most are rated for 60,000 to 100,000 miles, and replacing them early is pure waste. On the flip side, if you bought a used car and you don't know the service history, treating it as if the plugs have never been changed is the right call regardless of mileage.

Frequently Asked Questions

How much does a tune-up cost at Mr Automotive Repair in Gainesville, GA?

Our tune-ups range from $149 to $399. The lower end typically covers a four-cylinder engine with standard spark plug replacement and basic inspection. The higher end applies to vehicles with six or eight cylinders, hard-to-access plug configurations, or engines that require coil replacements in addition to plugs. We give you an exact quote after a quick diagnostic scan — no guessing, no 'starting at' bait pricing. Everything we do is covered by our 12-month/12,000-mile warranty, so if a part we installed fails within that window, we stand behind it.

Do I really need to replace all the spark plugs at once, or just the bad ones?

Technically, you could replace just the misfiring cylinder's plug. Practically, it's almost never the right call. If one plug has worn down to the point of misfiring, the others installed at the same time are in similar shape. You'd be paying for labor twice inside of a year, and the remaining plugs will start causing issues shortly after. The only exception is if we find a plug that failed early due to an underlying problem — like a leaking valve seal or coolant intrusion — in which case we need to fix the root cause, not just swap parts.

How often should I get a tune-up?

It depends on the spark plug type your engine uses. Conventional copper plugs need replacement around every 30,000 miles. Platinum plugs typically go 60,000 miles. Iridium plugs — which most vehicles made after 2005 use — are rated for 60,000 to 100,000 miles depending on the manufacturer. Beyond plugs, I recommend having your ignition system and fuel system inspected every 60,000 miles as a baseline. If you're experiencing symptoms like rough idle, hard starts, or reduced fuel economy, don't wait for the mileage interval — bring it in and we'll tell you what's actually going on.

Is a tune-up at an independent shop as good as going to the dealership?

In most cases, better — and I'm not just saying that. Dealerships use the same OEM or OEM-equivalent parts we do, but you're paying for their overhead, their service writer commission structure, and sometimes a technician who rotates between departments. At Mr Automotive Repair, the ASE Certified tech who scans your car is the same one doing the work. Our pricing reflects the actual job, not a dealership flat-rate book that assumes a two-hour job on a car that takes forty-five minutes. And our 12-month/12,000-mile warranty matches or beats what most dealers offer on routine maintenance. If your car is still under manufacturer warranty and you're concerned about voiding it, know that the Magnuson-Moss Warranty Act protects your right to have maintenance performed at any qualified shop.
