****I taped the TID and my car idles now! At first it idles at a solid 900...but after i drive it, it gets really low...almost to the point of stalling out******

The car idles fine when first started up because the thermowax is holding the throttle plates open a tad. As the water warms up, the idle goes down because the thermowax is letting the throttle plates slowly return to full close. That is normal.What is not normal is the idle being very low when warmed up. So.....set the timing,then set the tps, then set the idle per the fsm that is online and free to look at.

Come to think about it some more...and I think your problem may very well be the bac is not working. The bac has a duty cycle who's purpose is to maintain a 750rpm idle. See....http://www.teamfc3s.org/info/articles/idle.html

Does anyone know what $100T2 meant by needing to have your intake level?

I think he meant have to have the intake level stable..ie. no cracks or holes or escaping air.
