i dont drive my car right now cause i want it to run correctly before i do
i result to chevrolegs and the bus
but RotaryRocket88, so your FC doesnt have the nut im talking about, and the screw doesnt wiggle (with the vibration of the engine) out of correct adjustment?

thanx RR88
but if there is somthing to hold the screw from backing out, im still convinced i need a locknut (prefferably a ny-lock)
cause mine has nothing. and with the slight vibration from the engine its probably gonna back out a little over time (i would think 50 miles or so).
the spring puts tension on the bolt threads and that tension is against the threads of the threaded hole its in, but i would think its not enough tension to hold it in the exact same place. correct me if my logic is wrong.

jumped the connector and re adjusted the TPS, it still bounces.
i noticed when i turn the AC on it stops? ive cleaned out and tested the BAC.
could the leaqding coil not being in the car cause the idle to bounce?

The question you should be asking is why would it be good?
The leading coil does most of the work. If you run off the trailing coil only, you're running with severely retarded timing since it fires later (under most conditions). That will cost you power.
These are S4 TII timing maps, but you can see that split is as much as 15 degrees: https://www.rx7club.com/2nd-generation-specific-1986-1992-17/stock-s4-turbo-timing-maps-warning-those-stock-ecu-943159/.
