Tune-Ups & Ignition Service in Olathe

Tune-Ups & Ignition at Celso's Honest Auto Repair

A modern tune-up is all about the ignition system: spark plugs, coils, and wires. When these wear out, you feel it as rough idle, hesitation, misfires, poor fuel economy, and a check engine light that flashes under acceleration.

We replace spark plugs with the correct type and gap for your engine — not the cheapest plug on the shelf — and test each ignition coil and wire rather than replacing parts blindly. If only one coil has failed, we'll tell you that.

Skipping tune-ups costs more than doing them: a persistent misfire dumps unburned fuel into your catalytic converter, and converters cost many times more than a set of plugs. Staying on schedule protects the expensive parts downstream.

Not sure whether your car is due? Check your owner's manual interval or just call us at (913) 850-1750 with your year, make, and mileage, and we'll give you an honest answer and a quote over the phone.
