Quote: A few folks have told me it seems to have low vacuum at idle (around 15 in-hg by the dash gauge) but I've always figured those things were fairly inaccurate anyway.
15" is pretty much normal on a turbo car at idle.
Also, pull the dist cap and rotor off. Ck the relucter pickup wheel under the plate. I've run into a few over the years that the metal window would be loose causing all kinds of weird issues.
Turbo cars have a dual pickup, one for fuel injector timing and a 2nd for ignition spark
