what do you mean erratic? is the car vibrating at normal idle speed? a number of things can cause a harsh idle, it good be bad fuel, bad injectors, bad engine mounts.. check those, don't replace anything before you're sure what's causing it.

yeah. it is probably your vacuum lines; make sure they are all going some place; you might have a reverse vacuum on a line; does it start up fine and once it warms up it idles from about 1200 rpm down to almost stalling out?

Mine idles at times. Shuts off once in a while.
