'82 intercooled turbo.... I've been living with this problem for months now. Car would start right up then would bog something awful if I tried to take right off. If I let it warm up about 30 seconds, it would drive OK but would feel like it's starving for fuel at the top of the RPM range. If I drove it about 15 miles, the problem would completely dissapear. Thing was, I was going back and forth to work and it was only 10 miles each direction so the car ran crappy about 90% of the time I was driving it.

I was thinking it might be the little black and gray vacuum delay valve for cold acceleration enrichment down under the intake. I finally went contortionist on it today and yanked it out. It had no delay action whatsoever, in fact, it would just hold the vacuum and never let the pressure equalize. Luckilly, had a spare that worked lying around. Installed it and problem is completely gone. I've got full power all the way to 5.5K, even before it's fully warmed up. Eight months of grief for a $5.00 plastic vacuum valve. I'm glad is wasn't the control pressure regulator!

Hope this might help someone out there in CIS turbo land!
