Default Quick question.

What is the idle vaccum supposed to be? My car dies instantly, I think it may be a vacuum leak. Im getting -15PSI. I believe when it was running before it was -18? Anyone can chime in?

Thx guys.

you must mean 18 in. mercury... 18 psi of vacuum would be like 35 inhg of vacuum lol.

I idle around 19 to 21 inhg, or 9.8 psi of vacuum.
