bought a 73 mav the other day..250...well, anyways, the car sputters quite a bit..its running a bit rich, timing is advanced, plugs an wires need replacing, ect...the two problems i have are...I NEED the vaccum routing diagram...including the egr vaccum stuff...and also, the car runs GREAT with the hose going from the pcv, to the intake off, but it runs like crap with it properly connected...so, ANY help would be much appreciated
