Signs You May Need Engine Maintenance
Your engine might be due for service if you experience:
- A flashing or blinking check engine light

Our Engine Maintenance Services
Stonum Automotive provides a full range of engine maintenance services for all vehicle makes and models. Our inspections and repairs are performed by ASE-certified technicians using advanced diagnostic tools.
Fuel Injection Service
Your fuel injection system controls how fuel is delivered to your engine. If it’s clogged or malfunctioning, your engine may suffer from poor performance, high emissions, or even long-term damage. Our fuel injection service ensures proper atomization, clean fuel delivery, and peak engine efficiency.
Ignition System Inspection
The ignition system creates the spark that starts your engine. If components like ignition coils or control modules are worn, it can lead to delayed starts, misfires, or decreased power. We inspect the full system and ensure all parts are operating properly.
Ignition Wires & Cable Replacement
Worn or damaged ignition wires and cables can cause your engine to misfire or perform poorly. If your check engine light is on or you’ve noticed rough performance, we’ll test and replace these components to restore smooth operation.
Spark Plug Replacement
Old or fouled spark plugs can lower fuel economy and cause ignition problems. Our team provides professional spark plug inspections and replacements, using manufacturer-recommended parts to ensure reliable starts and efficient combustion.
