"there are rubber seals that get hard. You might take a look at these, I have found that wrapping the plastic peice that slips into the manifold with electrical tape will help out for a while"
hehe. have done this, and then ordered new seals.
"but did you also replace the cap and rotor?"
yup.
"My experience has been that minor vacuum leaks cause most of my problems.
"
still trying to track down leaks. i can't imagine that a teeny leak can make that much of a difference--if anything, the engine should run lean (looks like most vacuum is after the amm). still, relatively small leaks (small unplugged hose, bad foam seal) show up as major fluctuations in my vacuum gauge. normally, i'm about 1/4 into white. anyone know what the vacuum at idle should be? this seems like a good way to ballpark if there are any significant leaks...
