As far as I know there isn't a vacuum leak, I crunk the truck up after work last night and it started idling at 3000 rpm. I Dont know where to start with this problem but it isnt really driveable in this condition ): Please help me figure out where to begin.

 

The truck is a 1985 with a 2.3

 

Figured out that it was the pcv valve.. or the lack thereof. If my truck didnt have a pcv valve before why did this problem just show up?
