Sounds like the coolant temp. sensor on the engine? It's threaded into the inlet manifold.I can tell you that my 89/740 turbo Volvo wagon has one ,and mine was OK,but the wire was off and it ran very rich when disconnected.I couldn't believe how much this part effects the engine/fuel.So it leads me to believe that if yours is bad ,the same thing will happen! You stated that you replaced the air temp. ,But you didn't say anything about the coolant temp.You will have to remove the air resonator to get to it.Pull the plug wire while the engine is cold and then put the resonator and everything else back together and see if it still runs rich on start-up.This is basically your choke for start-up.If this is bad,it always tell the ECU. that its cold and to add more fuel.Let me know if this is it ,So I know
