Fixed my vac leaks and I still cant get an idle.
I adjusted all the screws and the tps and I still get a rolling idle.

Now I can get it to go down to about 1100 after I blip the throttle a few times .. but it goes right back up after a stop if I dont blip it a couple times again.

I think it has something to do with the throttle getting stuck ... errr this is driving me nuts.

At one point I adjusted it perfect so it hit 750rpm at idle .. but after adjusting it and blipping the throttle it went right back up to about 1300-1500 and started rolling again.

 

If its a steady idle thats high - a sticky TB or throttle plate set is a possibility. If it hunts or modulates at all then its an air metering issue - be it un metered air (vac leak) or bac problems.

Are you still running emissions?

 

everything is removed except for the bac

 

Could be the cruise control cable holding the throttle open or the cold-engine idle (thermal wax).
