New problem

I was getting the 332 error code regarding the EGR not opening and after doing so diagnosing, I saw that the red tube coming from the coffee can was cracked and the black one broke off as I was disconnecting from the can. Since I only had minimal time and about 2' of vacuum line, I plumbed a new line from the cactus-deal on the intake manifold to the FPR and a new line to the bottom of the EGR solenoid. The green line remained intact. This new plumbing had vacuum return to the EGR, but during my test drive the idle was good and regular driving was good. However if I was slowing to a stop, the truck would stall as I held in the clutch like it wouldn't catch itself to idle. Once home I played with the butterfly on the throttle body and when I barely BARELY open it the truck stalls.

Anyone have any suggestions? I pulled codes after and 111 on KOER and KOEO, but got CM 332, 334, and 311 (which I don't care about because I don't have the TAB & TAD)

Update: problem solved! It seems I had the vac lines to the EGR solenoid switched. Once I reversed them I don't get a light or stalling.

I was gonna say make sure you have the vacuum routed to the solenoid correctly, the EGR valve should be closed at idle and it sounded like maybe yours wasn't.
