Michael,
Your rough idle problem could be caused by loosely fitting throttle shafts.
Also, check for intake manifold gasket leaks by spraying quick-start fluid
while the car is idling. BEST to do it when the exhaust manifold is cold :*)
As far as having to adjust the clutch throwout rod all the way out, did you
replace the throwout fork locating pin? This is the one with a square head,
BL# 158777. This is typically broken and necessitates the fix you described.
If you do decide to pull the tranny and replace that pin, it can be driven
out by drilling a small hole thru the crotch of the throwout fork, just in
line with the pin, and then driving the broken end of the pin out of the
back side of the throwout rod. This will not compromise the structural
strength of the fork, and will make it much easier to remove the pin.
Engineering note: The failure mode of that pin is High Cycle Fatigue.
This is due to surface crack propagation. The way to avoid this is
to do like the racers do. Polish or shot peen the new pin where the old
one broke. Also make sure that the mating surfaces on the shaft and fork
don't cause abrasions on the surface of the pin.
Happy Motoring.
