I just got a 1983 Prelude to drive over winter.  I am having some
problems getting the thing to run properly.  I'll start it up and it'll
idle great for the longest time.  As soon as I drive it for a few
minutes it will start to struggle and the engine will die as soon as I
push in the clutch.  I can start it back up after it dies if I push
slightly on the gas but as soon as I take my foot off of the gas it
dies.  If I leave it sit for maybe 15 minutes it'll start up and idle
fine until I drive it again.  I can't seem to figure out what the
problem is.  I have replaced the fuel pump, fuel filters, air filter,
and plugs.  I also cleaned up the EGR valve and put in a new EGR valve
gasket.  I tested the EGR valve and doesn't leak and the diaphram open
and closes normally.  I checked for vacuum leaks and everything looks
good.  I replaced a couple of bad vacuum hoses (the 2 big ones on the
intake manifold).  What other things could I check?

Please CC my email address as well.

Thanks
