ok heres my other thread on the orignal problem and since then as you will read its gotten worse.......here is the tread...

https://www.rx7club.com/3rd-generation-specific-1993-2002-16/what-should-vacuum-readings-438794/

any ideas on what to do next would be a bit helpfull....

if you didnt read the post basicly all electronics work expect for the PFC and AVC-R. I was driving and had bad very very bad stumble at high revs and boost then suddenly my car stalled and shut down lost power to just the AVC-R and PFC.my car was tuned and all that 1K worth of break in..then this...no idea honestly

 

Why dont you check if you're actually getting power to the PFC...

 

theres about 4 connections coming into the pfc..which of those individual ports on those 4 connections would have power and which would not?
dont have the manual to look and see which ports are live or grounds ect..any ideas on which should always have juice?

 

anyone have experience with their pfc going bad?
