The statement made that vacuum leaks were constant and do not come and go is absolutely and totally incorrect. On these cars they commonly come and go when the PCV line at the intake attachment point bubblegums up to suck a slight hole in it. That hole can leak and then reseal to not leak as the little flap of torn loose material flaps around in the hole. I've seen problems then suddenly it straightens up and runs fine for several months only to do it again.
