AudiSport4000

Ok, here we go again. Was just going to take the 86 4kq to dinner a bit ago, car started up ok then idled near zero for a few seconds, then was fine. Drove to the beginning of the addition and the car had really no power, floored the gas and the car sputtered a bit, so I turned around and took the car into the garage. I popped the hood and chekced for things. The ISV is making a weird spontaneous clicking noise, so I hit it and hit it again. When I move the throttle very fast the car dies. I can restart the car, but it may take a bit of effort. Starting the car again, it will idle alright then once I manually flip the throttle all the way open the car chokes and dies.
Whats going on here? Any advice on what to check?

Bad gas?
Air filter clean?
Exhaust in good condition.
Sounds like fuel contamination.
