so over the weekend i installed the EGR block off plates on my N/A.

I thought i had all the hoses connect right, but when i accelerate the car just bogs. I've searched here and various other supra forums but have not found a Definitive guide/answer as to which nipples on the TB need to get covered, and which hoses i need to plug where.

Can anyone show me a detailed diagram or pictures of where i need to route which vacuum hoses? I read somewhere that after the EGR delete, i only keep a total of 3 hoses (?)





closed off this hose...


closed off the 3 on top of the TB, and kept the hose i'm holding connected



kept the intake manifold to fuel pressure reg hose connected..



closed off this nipple on the manifold..


can this hose just stay open?? i left it that way because i figured it was only leading to the now removed EGR lines.

that factory vacuum routing diagram only shows whats being used WITH the egr. I need to know what i do/don't plug up after i already removed the egr.

Question, did you put the resistor in place? Mine came loose once and I had a hesitation...?

what are you showing me in this pic?
what is that hose connecting to?

Its conected to the vaccum sauser in the Y pipe. It opens up (butterfly) in the intake. It must be connected. Its on the bottom left in that pic, thats why i included it in the pic.

^ok, thats what i feared, lol.

I guess now i'm gonna have to disco the y-pine again just so i can reach that saucer to connect the hose to it. i'm gonna go redo my hoses like yours and cross my fingers that it'll all work then

It's weird that it made you bog out like that, I wonder if the intake valve flapper vacuum line was the culprit?

LEX_MAN

I think it is, because i had to do the same thing with mine. I plugged it at first with all of my hoses running the same way, it bogged still.

YEAH..................so......basically my idle is acting up, again.

the rpm needle bounces up and down from a little under 1k to 1500k, and the car sounds like its gonna shut off sometimes. I checked all my hoses(even replaced with new ones) again, wtf am i missing??
