surging idle.

Good day folks,

I have done a ton of research and starting to lose it.

I figured that i might have to look elsewhere for some ideas as to what could be the cause, as my friend Kent says "sometimes it takes a second set of eyes to help fix the problem" and he has done so. Now that we got the car started the idle is a issue.

Any help would be great and I would love the feedback.

The detail are as such:
87 TII(s4) ecu, motor,tranny, wiring harness, TMIC and walbro 255 fuel pump. Got her to run but she is idling really rough. Boucing from 1000rpm to 1800rpms at a one second pulse. I have checked for vaccum leaks it doesnt appear i have any, my bac is not working i got that disconnected, runs cool (not getting hot), good compression 85psi frnt and rear, good oil pressure, fuel pressure is good, the ecu checks out fine as per testing with FSM sect4. The only think that is weird is the check connectors are not reading showing any response. no volts no nothing.
