Hi all

Could someone with a series 2 sc motor please check their vacuum reading at the main distribution (main port is where the brake booster hooks up).

I think I've either got a leak or a cluster issue.

My reading is ~15in HG'*

Thanks

EDIT: per conversion my gauge is pretty accurate. Now..I've got a vacuum leak and can't seem to find it.

Have tried carb and TB cleaner
Checked EGR
Replaced a cracked EGR tube.
Double checked vac lines.

Only thing that I'm not sure of.. i replaced the EGR tube and nothing changed.. have sprayed liberally with tb cleaner and no change.. hmmm

Ok.. unhooked all the vac lines including egr one at a time and plugged. No real change.

Well, I just did mine. About 19.5 inHg at idle with nothing turned on in the car. It went down to 17 inHg with the A/C on full and rear defroster on for more alternator load.

I'm not sure how accurate my gauge is, but it seems close to what I remember my scanner and MAP sensor saying the pressures were.

Hope that helps.

It does.. seems that I may just be paranoid.

Thanks/

Does it idle good, or does it seem to run rough?

Is there a reason that you suspect you have a vacuum leak?

He'* been chasing a lean bank code for a while. EGR tube was a recent find..I'm surprised that didn't help whatever the problem is, if there is a problem.

Well, I assume then that he'* already cleaned/checked/replaced the MAF, right?
