Ok, I get a rough idle after I have accelerated. (when I first start the car it idles fine) I also have poor performance and bad gas mileage. So I checked the EGR valve and it's fine. I propped a stick on the accelerator so it was runnin at about 3500 rpm and got no vacuum from the hose directly connected to the EGR. I then checked the hose connected to the valve control selenoid and got a very very slight vacuum. I followed that hose to it's connection under the throttle casing and found that the hose was cut there and the hose on the other side was also cut, just from old age I assume. Well, I think I traced the mess to the top of the carbon canister which was also holding a very slight vacuum.. I think.. I may just be crazy. So, what I need to know is if I should be getting a vacuum from the carbon canister and if so, which is the next hose I should check or, even better, where is the source of this supposed vacuum. Oh, and would those cuts in the middle of the system cause this, even though there is no vacuum from the carbon canister.

Thanks for any help
