Idle vacuum
#5
I did not mean to insinuate that I didn't understand how an engine functions. I haven't seen the car face to face. It's not my engine. I was talking with someone and they had this issue. I, however, have not owned a stock FD, or even one that was close to stock. Since I had no experience with the sequential setup and its various vacuum lines, I wondered if it were possible that something could cause a "low" or "no" vacuum reading.

It is conceivable that there could be no vacuum at idle, timing way retarded, and a big race port or bridge port, and some load on engine, etc.
But it's unlikely that all these conditions would met.
It's much more likely that there is a problem with the way it's being measured.
