Still running too lean, need help
HELLO ALL
And happy New Year! I have replaced fuel pumps, oxygen sensors, one fuel filter, EGR valve, and the EGR valve sensor. I’m 99% sure there are no vacuum leaks. However, I still get DTC TOO LEAN at both sensors. Next I guess I will replace the fuel pressure regulator. Any other suggestions out there would be greatly appreciated thanks.

How are your cats? You sure they're not plugged?
You might want to try TESTING some of these parts before spending all this money to replace them. A Haynes or Chiltons manual should give you all the electrical specs for testing your sensors with a multimeter and making sure they check out.
