I had initial problems with the install, once worked through issues everything appears to be installed correctly. The truck starts, but the truck idles high and fast, seems to increase. I have run through directions and troubleshooting guide several times. The support from the weber is horrible. Everything vacum releated is plugged, possibly missed something. I tried to adjust the idle and doesn't make a difference. I'm at a loss and not sure where to go. Please help, thanks.

 

I found with my Weber 32/36 DGEV kit that the return spring wasn't fully closing the throttle, like the spring wasn't strong enough. Next time it idles high, open the hood and see if you can push the throttle closed more; if the idle goes to normal range, you just need a stronger/better return spring. I tried a few, finally bought an assortment from Autozone "Help" section for about $6, and shortened the straight portion of one by cutting it and bending a new hook. That took care of mine.
