Sender unit switch under intake plenum. What is it?
 

There is a sender unit switch with two wire connectors under the intake plenum. What is it called and what does it do? The reason I am asking is that there was one connector off and the car was running fine. When I put the wire back on the terminal, when the car is hot and I try to start the car it will idle but when you try to rev it up it will feel like it is cutting off. After about one to two minutes it will clear up and run ok.

Thanks,
