Secondary Vacuum Solenoid - ZR-1 Net Registry Forums

jeasen · 08-04-2009

First I want to introduce myself, I use the screen name of Jeasen and I am new to this board. I am also a new ZR1 owner (1990 Red on Red). Although I have owned, maintained and drag raced Buick Grand Nationals for years this is my first ZR1.

I want to thank all the ZR1 guys that have gone before me and say Thank You for all the information available on the ZR1. The information is very valuable to a new owner. I was able to diagnose and repair my fuel pump problem for the cost of a couple of metal clamps. Thanks again for the help available in the How To section.

I am now trying to fix my Vacuum Problem and get the secondaries working. I started diagnosing the problem last night using information available on this board. It was not long and I found that the plenum needed to be removed. Once the plenum was removed I started checking the vacuum lines in different places. The plastic vacuum lines and the rubber connectors were all good. The actuators are both good (I was using a vacuum pump). The problem is the Vacuum Solenoid (Part #1999222).

Now my problem, I called the Chevy Dealer and the part is no longer available. I would like to know if one of you guys know of a replacement part that would work??? If not can I just remove this part and jumper the vacuum lines??? What has been you experience?? I feel the need for FULL POWER.
