Color & location of vacum side check valve?
I am trying to verify the color and location of the vacum side check valve.
This would be the the check valve that is associated with the two
"turbo control solenoids" and the vacum side of the "turbo control actuator."
One of the solenoids is the third one from the front on the solenoid rack
and I believe the other turbo control solenoid is under the UIM/extension
manifold behind the "wastegate and turbo precontrol solenoids".
I am trying to fix a secondary turbo boost problem.
Description of boost problem is
1st gear boost pattern is 11-5-5 most of the time less than 5lbs boost on secondary
2nd gear sometimes I get 11-6-10 sometimes 11-6-5 or less on secondary
3rd gear 11-6 sometimes 8-11 then dropping off
4th gear 11-6 sometimes 8-11 then dropping off
If more description is needed just let me know.
I have a 93 with catback and DP
Help is appreciated
Thanks

Somebody must know the color of the vacum side check valve that goes from the vacum chamber through the rats nest and to the extension manifold/UIM.
A little help please.
