[QUOTE="Joshua Vittitow 2, post: 995473, member: 70886"] My 04 is also having this problem. I replaced to fuel filter, at the recommendation of the auto parts store, to no avail. My neighbor has a really good OBD reader, so he looked at the codes for me. The codes are reading as Rich on both banks of O2 sensors, and high rail fuel pressure. It was also giving a reading of having 60% + ethanol, when it is only running on E10 (rather than E85). He thought it could possibly be a bad flex fuel sensor, however I have been unable to find any info on a flex fuel sensor. So my question I am now wondering if it may be the fuel rail sensor, and if this vehicle even has a flex fuel sensor? [/QUOTE]
