A 86 is DME and not sure what you mean by "thermo-valve". There is the ICV (idle control valve). It's a silver canister that bypasses the throttle body with metered air.
What do you mean by throttle sensor? The 3.2 has an idle switch and a WOT switch but no other sensors on the throttle body.
I would start with the usual suspects:
- make sure idle switch engages when throttle closed
- air leaks in intake track (gaskets)
- CHT sensor (if one-wire replace with newer 2-wire version)
- O2 sensor

Ingo
