Ok well I took the intake off my 90 vert and cleaned off the throttle bodies with some seafoam deep creep. Put the intake back together and started her up, and it will no longer idle. The car will stay running if I keep the throttle pressed and hold it at 1500rpms but the second I let off the gas it stalls. I drove it around to make sure I got all of the deep creep out of the intake and it drives perfectly fine at higher revs, but it still wont idle. So far I disconnected the battery and let it sit for about 30 mins and that didnt do anything. Help me out guys!

 

Vacuum leak, or any un-metered air for that matter will cause a no idle situation.

 

Yep right after I made the original post I went and found a few vacuum lines that came loose. She runs better than ever, thanks for the help!
