Martinez Tire & Auto Center does tune-ups at our O'Connor Rd shop in San Antonio. A modern tune-up replaces the wear parts that affect how your engine runs, usually spark plugs, filters, and ignition parts, and checks for the problems behind rough idle, misfires, hard starts, and lost fuel economy.

Tune-Ups
The old style tune-up, with points and carburetor adjustments, went away decades ago. On a modern engine, a tune-up means replacing the parts that wear out on a schedule and checking the systems that keep the engine running smoothly.
What that usually includes depends on your vehicle's mileage and maintenance schedule:
- Spark plugs, on the interval your manufacturer calls for
- Ignition coils or wires when they test weak
- Engine air filter and cabin air filter
- Fuel filter on vehicles that have a serviceable one
- A check of belts, hoses, and the battery
Signs your engine is due
- Rough or shaky idle
- Hesitation or stumbling when you accelerate
- Harder starts than usual
- Fuel economy dropping for no clear reason
- A check engine light, especially a flashing one
A flashing check engine light usually means an active misfire. Stop driving hard and get it checked soon, because a misfire can damage the catalytic converter. Our vehicle diagnostics service reads the codes and finds the cause before any parts get replaced.
Where to get a tune-up
Tune-ups are done at 12040 O'Connor Rd on the Northeast side. Pair it with an oil change and a battery test, especially before summer, when San Antonio heat is hardest on engines and batteries.
Questions we hear
How often do I need a tune-up?
Your owner's manual lists spark plug and filter intervals. Many modern plugs last a long time, but filters need changing more often, especially in dusty conditions.
Will a tune-up fix my check engine light?
Sometimes, if the cause is a worn plug or coil. The right first step is reading the code so we replace what is actually wrong.
Can a tune-up improve gas mileage?
If worn plugs, a clogged air filter, or a misfire were hurting efficiency, fixing them can help. It will not turn a truck into a hybrid, but it can bring mileage back to where it should be.
