Subject:      What is normal vacuum spec on 2.1L?
Content-Type: text/plain; charset="us-ascii" ; format="flowed"

Anyone ever put a vacuum gauge to their 2.1L?  I'm just wondering
what a normal reading should be?  My old reference material says
20mmHg for a 6cyl and 18mm for an 8cyl, not sure if I can exrapolate
this to the waterboxer.  I know for sure my breather pipe has a few
pinhole leaks causing some false air to enter after the AFM and I
thinks its causing some hesitation when engine is cold and a rough
idle (not real bad) when warmed up.  I'm thinking this leak in the
breather pipe should also show up as a low vaccum reading but not
sure what normal is.  Also not sure if this "leak" is being
compensated for by the O2 sensor or not (in longer inj time), I dont
know just how much out of whack the O2 sensor can compensate for.
