I am getting a lot of codes with rough idle and running rough under low load. Codes are p0174, p0300, p0306, and p2196. I know that the 174 is lean on bank 2, 300 is a random misfire, 306 is misfire on cylinder 6, and 2196 is stuck rich bank 1 sensor 1. I just can't figure out what is going on exactly. I have new coil packs and plugs, new pcv valve, the egr is functioning, maybe vacuum is the problem. I don't know for sure. This is the first ford I have owned and had problems to really deal with and had to diagnose. It's an 03 eddie bauer with the 5.4.
