so in a bid to assure myself an air tight engine, and
rule that out, i replaced the 4 hoses that attach the
the air runners to the intake manifold, and the
gaskets that hold the air runners to the heads. no
improvement. checked fuel pressure- 32 at idle, 38
with the vacum hose to the pres. regulator
disconnected. no problem. verified that the injectors
are working, spray pattern is good, nothing wrong
here. aux. air regulator is acting normal. temp 2
sensor is fine. ecu is fine. throttle switch is fine.
last time i pulled the plugs(month or so) they all
appeared to have been firing, discolored on the firing
end. so i think i am out of ideas here. here is what
happens with the van- start it up, cranks easily,
fires up to idle speed, then dies suddenly. crank it
again, and it will probobly die again, but sometimes
it will run rough for a couple minutes before dying.
once it is warm, it runs just fine, making good power
at 5 btdc, burns no oil between changes. plug wires
are almost new, cap, rotor,idle stabilizer, blah...one
more thing, since it will not idle cold, i have to
warm it up with my foot on the gas, about 2k rpm for 3
minutes and it is ready to go. while it is cold, the
rpm will fluctuate even though my foot is steady on
the gas, going between 2k and 1500 rpm, up and down
until it warms up a bit and then it steadies out...any
ideas short of changing the blinker fluid or muffler
bearings will be greatly appreciated, thanks
 as if i needed to add one more thing...i tried to
just set the idle speed high enough to get the darn
thing to run by itself, and even when i have the idle
set to 1.5k, it still will not run until warm. it will
run 1.5k once it is warm, about 10 min. later, but why
is this??? i set it back to spec since it did not help.
