timing freeze

[fixkick]

i suspect one other input to ecu is wrong, but id drive too. (id not let idle issues.,stop me,)

all way in, on the TB air bleed, means there is an air leak,
might be real (eg. cracked hose) or ISC does not close all the way , under command.
finding small air leaks is very hard.
any air leak will cause RPM to rise if the ISC closes down 100%
what happens is , add one small leak , and RPM rises, the ECU sees RPM rise above 800 and then the ECU closes the ISC to attain corrected 800 RPM idle (regulation)
if say the EGR leaks and RPm drops ECU , opens the iSC to correct this drop.
maybe your ISC leaks, like most old ISC do... most guys, just screw that screw in and get near 800 and say heck with it.
good luck to you.
your freeze is not working, it must hold steady, but may be the steering switch is stuck, in overload.? or IF A/C is on , (even with compressor missing, the dash lamp needs to be off or Idle is
1000 rpm. and youd have to screw the TB bleed all the way in. to get 800 )
is this an A/T car?
a A/C options?
and last is ECU P/N matching, A/T or M/T actual
i ask that, because many old kicks are running the wrong ECU.
56B30 - m/t
56B40 - A/t
the A/T has a PARK line that causes fast idle , not in park/neutral ( so engine dont stall as you select say, Drive (huge load)
