No high idle when cold

[fixkick]

welcome Steve.

the IAC under the TB is dead.
that assumes the engine is not flooding and misfiring (shaking too) at idle. (eg. fuel pressure stuck at 60psi , bad FPreg))
or grossly lean. say real low fuel pressure.
if the air fuel ratio is ok, then the IAC is stuck closed.

test in a pan of hot water

this hole must be open , cold until about 150F

dead cold engine.
off the huge air tube. up top
find a large rubber hoes that fits on that TB , rectangle port, and blow in that hole, if you can not blow into that hole , the IAC is stuck closed.

good luck and cheers !
