So today I got that intake manifold in the mail, and having one removed from the car gave me a clear view of how all the vacuum lines run. So, I went out to my car and definitively determined that the vacuum line going to the EGR valve (passing through the EGR-C solenoid along the way) is bad all the way at the throttle body. So, I was thinking of just buying a T-junction and some vacuum line and splicing the vacuum going to the power valve so that both valve use the same vacuum source. Keep in mind that the vacuum for the power valve comes DIRECTLY from the vacuum canister. I checked it and it pulls ~30mmHg. Do you think this will work? Or should I try and unclog the EGR's vacuum line (will be a PITA due to its location)? Thanks for any help.

 

nevermind?

 

WTF, chuck?
isn't egr vaccum ported?

 

EGR is controlled by solenoid, which is controlled by ECU. To clarify, both the EGR and power valves are controlled by solenoids, each with their own vacuum line going into them. What I want to do is use the vacuum line going into the power valve solenoid to ALSO go into the EGR solenoid (since the vacuum line to the EGR solenoid is bad).

 

but what brian is talkign about is what i was saying.

Powervalve = vacuum behind TB
EGR = vacuum before TB
