cold start problems

[olpete]

another cold start problem but I couldnt find one exactly like mine.I've got a 99 f-250 and even when it's in the 30's or lower when i let the heater light go out and crank it. It cranks fine but in about a couple of minutes it will begin to idle rough and cut off. A few times when I've been in a hurry and didnt have time to let it warm up enough when I take off it seems to be under powered and will run rough and cut off about the time it shifts into 3rd gear.When I plug it in at night it does not cut off after I crank the truck.Any help would be appreciated.

Maybe the ebpv is getting stuck closed?? When you plug it in the engine is warm enough for the valve not to open.

Sorry it took me so long to get back to you guys. I unplugged the EBPV and that did nothing but I guess if it's stuck closed would that even matter? Is there a way to check if it is stuck closed short of taking apart alot of stuff? Also the other day when I left work it was around fifty degrees and I hadnt had the truck plugged in and gave it time to warm up. It didn't cut off while idling but after I took off it did the cut off around third gear thing. Then it's hard to crank back up but once it idles a little longer it doesn't cut off anymore but it ran very sluggish like something is holding it back. Thanks for any help.
