huge errors.
so i bet if you screw the bleed screw in all the way it never locks in at 800 and smooth,
that is sign of
the IAC is stuck open (180F coolant and good hot engine) this valve is 100% thermal active.
or the throttle plate is blocked open some how.
all other air leaks cause too low idle.
what i do is block this hole here.
with putty or tape somehow. (my 97 had this bad. and was stuck 1/2 open)

you cant run the engine with the pipe off or the MAF goes to limphome,mode, and no idle controls, etc.
so i had to block it , then put pipe back and test, then remove it later.
if this valve stick open it will scream. that hole is huge. there. lots of air possible.
