Smog Mart Inc, Smog and Automobile Repair Center
Scheduled maintenance, done right

Tune-ups in Sacramento. Plugs, coils, filters, done on schedule.

A modern tune-up isn't points and a carburetor. It's spark plugs, ignition coils, air and fuel filters, fluids, and a proper inspection. Done on schedule it keeps the engine efficient, which is exactly what a smog analyzer is measuring.

Worn spark plugs removed during a tune-up at Smog Mart
What a tune-up is now

Three things it covers

  1. Ignition

    Spark plugs and, where needed, ignition coils. Worn plugs cause misfires, rough idle and higher emissions.

  2. Air and fuel

    Engine air filter and fuel filter, so the engine breathes and burns the way it was designed to.

  3. The look-over

    Belts, hoses, fluids and battery checked while it's on the lift. If something needs attention we tell you why and let you decide.

What we replace and check

Due for maintenance and a smog?

If scheduled maintenance like spark plugs or filters is genuinely due, we can handle it around the same visit as your smog check. If the check engine light is on, or the vehicle fails the smog, we diagnose the real problem rather than guessing that it needs a tune-up.

Tune-up or diagnostic?

A tune-up is maintenance. If the car has a check engine light, a rough idle that came on suddenly, or a misfire code, that’s a diagnostic first, so you don’t pay for plugs the car didn’t need. Pair the tune-up with an oil change and it’s one visit.

Common questions

Tune-ups questions

Will a tune-up help me pass smog?

It can, if plugs or filters are genuinely due; worn plugs and dirty filters raise emissions. It isn't a guarantee, and it isn't something to buy just because a smog is due. If the check engine light is on or the car fails, we diagnose the actual problem rather than guessing it needs a tune-up.

How often do I need one?

We go by your manufacturer's schedule, not a sales quota. If you're not sure when the plugs were last done, we can pull one and show you.

How much is a tune-up?

It depends on the engine: how many cylinders, what plugs it takes, and whether coils are due. We quote it for your vehicle before we start.

My engine is misfiring. Is that a tune-up?

Sometimes. A misfire can be a plug or a coil, but it can also be a sensor, an injector or a vacuum leak. If the check engine light is on, start with the diagnostic so the right part gets replaced.
