    lately i have been getting a pending trouble code, PO136, for my 2001 2.7L. The ultra guage tells me i get the pending trouble code only when im in stop and go traffic, not at any other time. it may happen once a week r once every 2 weeks. I just clear the code but is this something that needs to be looked into since its only pending? Also, i do not get a CEL and im still getting good MPG. sometimes the truck will idle a little low (650-625rpm)when the A/C isnt running so i dont know if this has anything to do with it but it has been idling like that ever since i canremember and i never has this code pop up

    *also, the truck doesnt have the rear Cat but i do have the URD sensor simulator and it has never given me problems

    Bet it has everything to do with removing that rear cat as this refers to the O2 sensor furthest removed from the engine. I would guess it's probably not anything to worry about unless you have emissions down in Louisiana.
