I am having an issue with a my 2006 Quest.

Scanner reads:
MAF (lb/min) 0.421
O2B1S1 0.385
O2B1S2 0.180
O2B2S1 0.750
O2B2S2 0.220

Freeze Frame DTC:
DTCFRZF P0171
FUELSYS1 OL_FAULT
FUELSYS2 CL
LOAD_PCT 15.3%
ETC 178 C
SHRTFT1 0.0% >>>>it was really at 25% prior to DTC
LONGFT1 14.1%
SHRTFT2 25.0%
LONGFT2 13.3%
RPM 775
VSS 0 >>>>>parked
TP 2.7%

Prior to this DTC there was one other P0174. The P0171 and P0174 did not occur together as best I can tell. However,I did erase the P0174 before the P0171 occured. I did have a misfire pending P0302 but it no longer exists. Of course this is all generic data, but from researching the issue, the best I can tell is that the intake gaskets need some attention? I have not been able to locate an intake leak, however. (propane, carb cleaner) Not saying there isn't one, I just can't find it. Any ideas? I'm pretty sure the sensors are fine. I am stumped and of course have to pass an emmisions inspection.
