• A fuel odor may suggest issues with the injectors or fuel lines that need immediate attention.

Step 6: Assess Fuel Consumption

• Keep track of any significant increase in fuel consumption.
• An inefficient injector can lead to higher fuel usage, indicating a need for inspection or replacement.

Step 7: Evaluate Emissions Test Results
