Tune Up in Fortuna, CA
A tune-up is a refresh for your engine's ignition and fuel systems. Over time, small parts wear out, like worn-out shoes, and replacing them restores smooth, efficient running.

How Tune Up Works
Each time the engine fires, an ignition coil makes a high-voltage pulse and a spark plug turns it into a spark that lights the fuel and air. Spark plugs wear down after thousands of sparks. Filters clean the air and fuel going in. When these parts get old, the engine can misfire, idle roughly and use more fuel.
Why It Matters
A worn ignition system wastes fuel, lowers power and can damage other parts such as the catalytic converter. Replacing plugs and filters on schedule keeps the engine smooth, saves money at the pump and helps it last.
Warning Signs You Can See, Hear or Feel

What We Do at JC Auto
We replace spark plugs, inspect coil packs or wires, and replace air and fuel filters as needed. We check belts, hoses and the PCV valve, scan for codes, and road test for a smooth idle and acceleration.
Words You May Hear
- Spark plug: A small part that makes the spark that ignites the fuel.
- Ignition coil: A part that boosts battery voltage so the plug can spark.
- PCV valve: A small valve that lets engine gases vent safely.
How Often Should This Be Done?
Many spark plugs last 60,000 to 100,000 miles. Follow your owner's manual.
Common Questions
Will a tune-up fix a rough idle?
Often, if worn ignition parts are the cause. We confirm with a scan.
Do new cars still need tune-ups?
Yes, though the parts last longer. The service is now part of scheduled maintenance.
