help i need to know where to get a boost control solenoid for my 1994 bonnie or what bcs off another gm will fit my year

Its been a couple years since I ordered mine but it looks like neither GM parts Direct or Rock Auto has them anymore but you might want to give them a call. I did see one on Ebay so you might want to check them out.

I found this old post. Check out the last entry.

Do you have a salvage yard near by? I'm stopping at one tomorrow, I'll try to remember to look.

no the only salvage yard is 85 miles away. i live in a one horse town but imma try and get a hold of one since i can use 96 and up hell ill try anything. im only gettin like 4 psi at wot and i did the plug test and got at least 7 or 8 psi. i have a fwi so i should be getting more than 4 psi is what im thinkin the bca moves freely no binding or anything thanx fellas and dan if you did get ahold of one hell ill buy it from ya just let me know how

Watch the boost valve when you give it gas. Does it move all the way? If so, the gauge is simply not reading right. If the valve does not move all the way then the boost solenoid or the valve is bad.
