Vacuum Leak!!!! Someone please HELP!

[Atticus_]

ok i have been trying to track this damn leak down for days now! my car idles at around 2500rpm/3000rpm and can run about 30 seconds before it stops. I have all emissions removed oil metering system gone but the oil injectors are still on but blocked with vacuum block offs. i got a new gasket for the upper and lower connection and replaced it all i did before the leak started was pull the upper intake off and replace my primary injectors. i cant seem to find any signs of a leak any place. Is there any easy way to find vacuum leaks? i am lost on this one.. i have taken off the intake about 10 times. can you tell by how high the idle is as to how bad the leak might be? my boost gauge reads around 18in/hg at 2500rpm

Check the TB.

Is your Idle adjusted after removing emissions?

Also check the LIM on the firewall side.

IS your brake booster line dried and cracked?

Did you replace all the vac lines with new silicon ones?

How well are the BAC/EGR and stuff blocked off? Did you use a gasket between the metal block off plate and the manifold??

let me correct myself. emissions have BEEN removed previously and everything was working fine. the throttle is closed and hasn't been messed with.

i even blocked off the booster line at the manifold to make sure it wasent that, and it made no difference.

i dono, i guess i will have to just go by all new blockoffs for everything and re run all the lines the best i can. i am going to go ahead and assume that it isnt the block off plates because they are all sealed with gasket sealer and that it isnt the gasket i got for the upper and lower intake connection.
