do you mean throttle body? you have mfi ? I have an 89, think most should be the same, unless yours is california.

i would think that the fuel regulator has vacum or it wouldn't run, same with the map sensor(vacum hose from thottle body to map sensor). You need to have a vacum source to the egr valve solanoid and then to the egr valve.

[89ltd]

also a vacum source to the air box cover where the temp sensor is , to one side, then from to the other side to vacum door on the front of the air box.
