I've recently replaced the EGR valve and the tube on my 4.0 and now I am getting a few engine codes... 1. Bank 2 sensor 1 slow response, 2. Bank 2 too lean, 3. OBD test incomplete. The O2 sensor is switching from rich to lean and I don't see any damage on the wires. Is there supposed to be vacuum at the EGR when it's idling? Any help with this issue would be appreciated!!
