I have a 2000 v8 EX AWD. It started throwing a P0174 Code (pending) & P1151 (Current) 2 days ago. I did some digging, cleared the codes and data logged. The P0174 came back and it occasionally bogs and loses power. Many of the things I've read state clean the MAF, look for vacuum leaks; those things should affect both banks though.
Fuel trims and O2 sensor 1 look good on bank 1.
Fuel trims and O2 sensor 1 on bank 2 are a different story. At times they look normal, then O2 goes low and fuel trim maxes out. it's intermittent. I'm including a pic below of the data, in this case it seems to get worse as we drive.
My plan is to swap bank 1 O2 and bank 2 O2 to see if the trouble follows the O2 sensor, then troubleshoot accordingly. I did look at the connector and wiring, it appears OK and connection was solid. There is some fluid on the CAT as it crosses under the engine/ tranny near that O2 sensor, could have contaminated the O2 sensor / wiring?
Any other suggestions to troubleshoot??
