Maybe I haven't found it yet..or maybe it doesn't exist...but I was thinking one way to help some frequent asked questions is to upload whatever diagrams people have and stick them in some kind of section where a user can click on which trans am/firebird they have and what year.. I understand there is a search forum feature but I figure there might be a good bit of this stuff floating around that people are not aware of.
I'm trying to find a vacuum diagram for a 1977 trans am 400 engine with the 4 barrel carb automatic. (has a Z in the vin #)
it has a miss in it's idle..and when we try to connect all the hoses to the correct areas (or what we think is correct), it idles like a kitten, until you tap on the gas (not necessarily hard) and let off then it just stalls out on me...also the transmission wont shift and it starts to rev a little hard at 35 mph. I'm quite sure that this miss is in the vacuum lines because everything else has been timed right, the carb is a fresh ordered rebuilt quadrajet and the engine has been rebuilt.
is there any diagram on here that can help me?
