coolant flowing between iac and isc ?
#13
ohhhhhhh -30c, burrrrrrrrrrrrrrrrrrrrr,
the starter, if really bad, might work if cleaned. the solenoid, could use cleaning and re-lube on its back side, rust, filth and ice, all make it jam. use cold rated grease.
same with the spark, i clean them lube em then try them.... (use oil based paint solvent, sold in walmart cheap. by gallon, this is old name Stoddard solvent..)
the vsv can break many ways.
some have 3 vacuum tubes.
my photos show all this,
there a 2 red ones.

depends on which one, and what tube broke, photos work best, so I can SEE it.
in this photo ,
left (facing engine) is EVAP VSV
then front red= dash pot. fast idle.
and rear blue.. EGR

in all cases,
if the input vacuum brakes engine sucks air, and races fast and that feature is dead. races even parked.
if the output nipple breaks, that feature breaks and if active driving, as all 3 are, engine races driving...
i think the 8v has only 2 way valves.
one hose bottom , and one top.
here they all are.

now the vent top with filter
this allows the output port to go open , when vsv is not energizes,
this prevents trapping air in the output line. so is 3 way in that regard.
open
closed and vented.

tell more get more. need which one?
and what damage exactly.

the top filter missing will not kill the valve. (now)
the filter ois so it dont suck in dirt (in vent mode). and jam it later...

evap open running
egr opens under running and under load for sure. and never wide open throttle.
the dashpot pulls in 3-30seconds after starting, ending cold fast idle start time. if you lose vacuum to the DASH pot , it slams the throttle open. and on mine hunts like dog, surges.
