P2099 and P0174 fault codes
Posted: Thu Jul 26, 2018 4:30 pm
Hey,
I have a 3.8 jk. And have received the fault codes - see attached.
I've changed the O2 sensor pre and post cat on bank 1, and have recently stripped and cleaned the intake manifold.
Using the superchips, I brought the ECU back to stock settings with the same result...
Any other suggestions on what I should look at to sort this out??
