variable resistor responce?, Initial coupler set? FSM?

[atsronnyats]

I wanted to go threw threw with the idle speed mixture setting procedure but i have two questions/comments

a. i have no response from variable resistor what so ever (when adjusting) and would like to know if you all had any ideas about the reason for that. Just so you all know i did take it off and verified the resistance across both circuits and it checks out.

b. My second question also pertains the FSM procedure. The first step in the procedure is to attach a jumper wire to the "initial coupler set." My question is where is it. upon searching the issue some people post its next to the coolant reservoir. According to the FSM photo this would seam correct but the photo also shows the battery inches away. I haven't seen and fc3s with a coolant reservoir in this position and there is no coupler to speak of in this suggested position (next to accumulator/drier). having said that, I have to assume the "initial coupler set" is the green plug next the dianostic plug and the leading coils. thanks for clearing this up in advance
