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.
