Just yesterday i was driving down the road and the check engine light came on out of nowhere. No change in drive-ability, still smooth as silk. Had it checked out at Auto-Zone and it pulled up a 'P1131' code and he said it had something to do with fuel. Anyone have any clues about this? Has anyone had this happen?

Fuel sender circuit? My CEL goes on and off all the time, and I constantly have the Fuel Sende Circuit failure code even when the CEL goes off. Hasn't done anything bad to the car...yet

Chris, P1131 is Lack Of HO2S11 Switches - Sensor Indicates Lean (see P2195) which is basically your bank 1 O2 sensor. When checking P2195 it shows O2 Sensor Signal Stuck Lean Bank 1 Sensor 1. So it seems to me to be a O2 sensor failing.

PS: Mods, please move to Problems.
