I tried a search but came short of an answer. My car at idle (850RPM) with all my accessories on (Defrost, Heater Blower, and lights) pulls about 15 or so on my Autometer gauge, but I believe I may have a vacuum leak somewhere. I also think my TPS is outa wack because it has the common idle and acceleration misfiring. But when my idle jumps to 1000RPM with all the accessories off it pulls 18. I don't think my compression is low because the car runs great aside from the miss. Just thought I would ask. BTW it's an 89 S5 with a freash Jspec TII installed.

My 91 TII pulls ~18 at idle according to my Autometer boost gauge, thats with a Mazda Reman with around 15k miles on it.

about 15 for me as well at about 800 or so. it really depends on RPM, the higher the idle the more vac it will pull.

Thanks for the reply. I've checked the posts and there is some very interesting info there. It sounds that my vacuum could be a little low, but I think I have a little vacuum leak somewhere.
