100730, vacuum at idle
Posted by ian_12, Aug-30-06 09:05 AM
model info, 95 gs turbo. i rebuilt the motor about 20,000 miles ago.
the problem is, it seems to have some low vacuum at idle. its like around 12 in. hg, when i normally see like 20-22. the car does idle like it has harsh cams/cam timing out, but isnt. when in gear and coasting, i was told it pulls like 20 in hg. i havent compression tested it yet, and hope that there isnt a problem within.
but you guys pulling like 20 in hg at idle?

mine only pulls 12 at idle cold, maybe 14 when its as hot as it gets, but it idles totally fine. I have no idea why it does this. maybe I've got it tapped off a bad spot.
