86 Diagnositic Test Port test for continuity on B/A to C
I need some help if someone would go out to there car or know this for sure and provide me with the following.
If the Tps switch is not closing at idle and Wot or cannot be bypassed to adjust air bypass, "by this procedure listed below", the idle will go crazy, which is my issue after intake rebuild.
My test connector, located near the Temp II sensor the one with the rubber cap the folds down is the one I am talking about.
The manual calls for B to C to be connected with a wire and adjust idle on Throttle Body. If you turn the idle Adj screw it all the way on car should stall with this wire connected. I can test this directly on the discenagrated connector and to the computers and they work. From what I remember I read a direct short should appear at B to C at idle and A to C for Wot on the test connector. Now all I have is ground at C and from B to C at Wot is showing continuity which I belive not correct. A to C does not show continuity.
Would someone be kind enough to go to there car and test this and tell me what they found?
PLEEEEEEEEEEZE

A is a test terminal which comes from the LH. I don't know what info it is supposed to provide.
B is wired to the full load (WOT) switch, it will show ground after 2/3 throttle, otherwise it is open. C is ground. If you connect B to C, then the idle should be 680 ±40, if the idle switch is also working.

With B and C connected this will bypass the Air Control valve to adjust base idle.

B -> C, idle switch closed
...
Idle + WOT
LH: disable idle air controller
EZF: retards from 10° to ~6°
