thank you for your replies...I really appreciate this help... I will replace the pre-filter
seal, as I haven’t replaced that. The shut-off valve does leak slightly, but it has been this way for a while already, and hasn’t been causing this issue before. I did replace the vac lines, if I remember correctly there we three, along with the two electrical plugs. I was very carefull, as I know these things are rather fragile, I did not torgue the delivery nuts to specs, as I don’t have any material with specs to go by, but I am confident in my hands…I don’t see how the small amount of air can cause this car to top out at 45mph though. Any more suggestions are greatly appreciated…


BTW. I replaced the evaporator on this car this summer, took about 15 hours of work, but the AC works great...now If i could get this engine ticking correctly...lol
