POOR GAS MILEAGE AND EXHAUST FUMES IN CAB

2001 Dodge Dakota

Engine Performance problem
2001 Dodge Dakota V8 Two Wheel Drive Automatic 112000 miles

as stated above these are just two of the symtoms
i have replaced many sensors and do not seem to have a vacuum leak. Exhaust smell is really strong when heat is on. Also have p0171 and p0174 lean on bank one and bank two. What could be causing all of this. I am only getting 8.5 mpg.

Hi truhnke, Welcome to 2carpros and TY for the donation

P0171/P0174 Lean conditions could be caused by one of the following

1. Vacuum leaks
2. EGR and PCV valve.
3. Low fuel pressure.
4. Dirty fuel injectors.
5. Mass Air Flow Sensor.
6. Oxygen Sensor.
