What a modern tune-up covers
A tune-up typically involves inspecting or replacing spark plugs and ignition coils, checking the fuel system, and looking at the parts that affect how the engine runs. The exact scope depends on your vehicle and its mileage.
When it's due
Rough idle, hesitation, a misfire, or a drop in fuel economy can all point to ignition or engine-performance wear. A diagnostic scan helps identify which components need attention.
We confirm what your car needs
We don't replace parts blindly. We inspect and diagnose first, then recommend the tune-up work your vehicle actually needs — whether that's spark plugs, ignition coils, or fuel pump service.
