Tune Ups in Rexburg

Care for your vehicle

A tune up should match your engine’s maintenance needs. We offer tune-up service as part of ongoing vehicle care.

Modern vehicles do not all need the same tune-up parts or intervals. Scheduled ignition maintenance is different from diagnosing an active misfire or stalling complaint.

Before your visit

Bring service history and mileage. Describe poor starting or running separately from routine maintenance so an active fault is not mistaken for work that is merely due.

Tune-up work should fit the engine

A modern tune-up is not the same fixed list of parts for every vehicle. Spark plugs, ignition components, filters, and scheduled inspections depend on engine design and maintenance history. Rough running or poor acceleration may also require diagnosis beyond replacing routine service items.

When to arrange an inspection

  • A scheduled spark-plug or filter interval
  • Rough idle, hesitation, or hard starting
  • A change in fuel economy or engine performance

Separate scheduled care from a fault

Bring the vehicle’s mileage and records of previous plug or ignition work. Ask which maintenance items are due and which findings require separate diagnosis. Replacing every ignition component is not automatically necessary. A flashing check engine light with rough running should be treated promptly because continuing to drive can cause additional damage.

Questions about Tune Ups

Troubleshooting Guide

View All Troubleshooting Guide
Why is my check engine light on?

The computer has detected a monitored engine or emissions concern. The code alone does not prove which part failed. R & S Automotive Center offers diagnostics to investigate the condition and any symptoms you have noticed.

What should I do if the check engine light flashes?

A flashing light can indicate a misfire capable of damaging the catalytic converter. Avoid heavy acceleration, stop safely, and arrange assistance if flashing persists or the engine runs poorly. Discuss diagnosis with R & S Automotive Center before continuing the trip.

Why does my engine idle roughly?

Ignition, air, fuel delivery, or mechanical problems can all affect idle quality. Tell R & S Automotive Center whether the engine is cold or warm when it happens. Severe shaking or stalling warrants stopping safely rather than repeatedly trying to drive through it.

Why does my car hesitate when I accelerate?

Hesitation may involve fuel delivery, ignition, airflow, or engine controls. Record when it occurs and whether a warning light appears. That information helps R & S Automotive Center investigate without assuming a tune up or fuel additive is the answer.

Why do I smell gasoline near my vehicle?

A fuel odor can indicate a leak and a fire hazard. Stop safely, turn off the engine, keep flames and sparks away, and arrange assistance. Do not restart to look for the leak; contact R & S Automotive Center about repair after the vehicle is safe.

Service Questions

Can I schedule a tune up?

Yes. R & S Automotive Center offers tune ups as part of vehicle maintenance. Bring service history and mileage. Describe poor starting or running separately from routine maintenance so an active fault is not mistaken for work that is merely due. Call 208-356-0786 to discuss your vehicle and arrange service.

What is included in a tune-up?

There is no universal package. The vehicle’s service schedule, engine design, mileage, and condition determine which plugs, filters, inspections, or other work are appropriate.

Will new spark plugs fix every misfire?

No. Coils, fuel delivery, wiring, air leaks, or mechanical concerns can also cause misfires. Diagnosis helps determine the actual cause.

How often should spark plugs be replaced?

Intervals vary substantially by engine and plug specification. Use the manufacturer’s schedule and records of previous replacement rather than a single mileage interval for all vehicles.
