stalling

[jummer]

Had my expedition start stalling one morning. I put my code reader on it and came up with code 1151 and 1131. Put new o2 senors on and still the codes remained. Got to reading in here and came up with the hose to the pcv valve had came off. It did the trick. dont remember who had sugested that to another person in here but it worked for me. Thanks for the help

I am having the same problem, where is this hose and valve located?

i belive it's on the passenger side valve cover, and runs back to the rear of the intake manifold, under the idle air controller there's a 90 degree connecting boot that will rot out over time, cause's major vacuum leak

So if there is quite a large hole on that hose were it connects to the valve cover, it could cause some major crap eh? Well, I really don't know where to begin. I have codes 0153, 1131, 1151, 0171, 0174, 1132, 1152. any idea of what I need to check for once I replace the above mentioned hose?
