Hey guys whats the normal vac on our cars at idle again???

I think mine dropped down...it is currently at 17 i think it used to be higher than that but i may be mistaken....just taking the proper precautions....

 

i think vac usually sits about 20 at idle

 

yea 20 isusually where thevac is i noticed with mine it use to bounce between 18 to 20

 

so any ideas why mine is at 17??? what should i do?? i thought it was off....i havent changed any lines around i wonder why it dropped to 17?

 

it could be the weather or maybe you sprung a leak somewhere check all of your vac. lines from what i've heard the car comes stock with two boost leaks i been told the perfect fix is a one way check valve i know one of them is off the brake booster but i'm not too sure where the other one is.

and speaking of vac. problems the guys who installed the turbo hooked my boost gauge up to the turbo so now its only reading boost it doesn't read vac. they said there was no spot to hook it up to the vac. lines so i was thinking of putting a T off of one of the vac. lines would this help?
