My idle is funky on my car. When it warms up it wont stay started. The screw on the top of the top mainfold is all the way out and it still doesn't wanna idle. Can someone please help me out here.

 

I'll place bets on you have a vacuum leak. I have an '87 TII which I got back on the road after a long time-out on the driveway.
It wouldn't idle for ****. I took the top end apart and replaced *all* the rubber - vacuum, water and fuel.
Idle was then 1500rpm instead of 2500. Much diags later, I found another air leak between the AFM and the turbo inlet. Sealed that up and idle is rock solid at 850.

Before you try *anything* else, replace all the hoses, and fix any tears in the big ducts between the AFM and the motor.

I'll lay the first-born on tha fixing it.

... Don't forget to replace any loose clamps on the ducts. think tight and sealed
