2 weird (minor) problems

[whytry]

For the idle screws, I would turn them all the way and back them out 1-1/2 for starters. Then adjust from there. Do you have a way to check vacuum @ idle? That would get you an idea of where to go in terms of keep taking them out and how far to go. Make a 1/4-1/2 turn if vacuum increases then go to the next screw and do the same until the vacuum drops then go back to where the vacuum is highest. Then I would check your idle, it might be higher or lower then before.
