I have fuel economy less than before.
Ignition plug changed, tires pressure okay and no (check engine) activated. How can I start to diagnose the problem (what the plan sequence)?

Good morning,

Driving habits are the most common reason for fuel mileage.

Other possibilities.

1. Alignment and tires.

2. Transmission. If the shift point is off, you will use more fuel.

3. Tire size. If you changed tire size, it will affect mileage.

4. Filters. Make sure fuel, air and all filters are clean.
