I have a 92 RS with 3.1L MPFI and all the vacuum hoses are off and I don't know where they go.I looked in the Chiltons but the diagram they give is not accuart. My engine has more hose than their diagram shows.So if any of you have the same car as me or know someone that does if you could look at the vacuum hoses and draw a detailed diagram I would be greatly in you debt.

 

i don't know what to tell ya bro, try to find open connections?

wait for TomP or Karl, they know how to help you.

i could see in my mind where mine are, but its hard to explain.

i do some searching...

Seriously
Chilton big book is the best source easy way.
Other way is just as easy, tho
Take a ice cold soda to the local GM parts counter person you like and ask them for the PVC diagram hose routing illustration.
The one showing the EGR set up.
While you're there, please buy the GM Performance Parts Book for the measly $6.
You'll like what ya read.
Gives ya lots of knowledge of what your ride can attain.
As it was designed by the GM engineers.
And they wrote this book.

 

check on the underneath side of your hood. There should be a vacuum diagram sticker affixed there for your individual car.

 

Funny you mention that.
OF all the cars I ever owned or recall in family.
Only a few cars had those stockers.
Only the new ones from the dealer.
My 85 Firebird is repainted
My 85 S-10 Blazer was in a front end accident before I owned it.
My Wife's 1968 Camaro has the original 1968 pollution sitcker on her car tho....
I recall one time trying to get my Blazer "smog hose sticker" from the dealer.
He kinda laughed.......
BUT the parts counter printouts given ya are the perfect-best-most accurate solution. And free.
I have one for both 1985 cars.
They show everything in complete understandable detail.
Also ask for the part number printout page, too.

 

Where do i find a GM parts counter? Do i find a chevy dealership or something? Thanks!!

 

dude that post was like 5 years old and unfourtunatly ked85 passed away. if it wasn't for that guy i wouldn't have a 3.4 but u can find a parts desk at any gm or chevy dealer but if u need parts u might as well go for the after market parts they're cheaper than OEM (most of the time)
