It's a great mpi engine. and very reliable. just keep it cool. and it lasts.
ok , seems the ISC is stuck. (electric, on left side of plenum box)
the IAC can not be fixed, (wax pellet inside.)
thats a bad trick blocking the PCV, that causes crankcase pressure to build, and oil leaks, from seals
and also forces the intake side of PCV to run backwards,
pcv is cheap, like $5 USD. and the hose. any smog hose there works, sized right.
so you can get 800 rpm hot? with that bleed, if yes, then does turning on Head lights and the heater blower at the same time give you , 800,
might sag to 700 or come back to 800 fast, 1second time? this is ISC regulation working.. and a test.
you now found 2 bad things, egr defeated, (no big deal) and PCV defeated, good going there....!
cheers !
ps
the other things to be sure of=?
engine reaches 180f (82c) and holds, not dropping,, and the thermostat well, it fits in a well if that well (pit rim) is 4mm deep it must have a rubber ring on the thermostat. if 1mm rim , paper gasket only. (cant be mixed the 2 or wrong)
or it floats and bad happens.
