My 92 chevy s10 4.3L is using to much gas I can go 18 miles and it uses up about 5 dollars worth of gas. I just did a tune up.

Let's try fuel there's a lot more areas that can reduced fuel economy-could be running rich due to the following

1. Excessive fuel pressure can be cause by restricted fuel return line or defective fuel pressure regulator.
2. Defective Oxygen Sensors.
3. Leaking injectors and fuel pressure regulator.
4. Coolant temperature sensor out of calibration.
5. Restricted air intake system.
