I'm sorry that this problem isn't one that can be answered without looking and listening . . . If you are able, please drop it off some weekday morning and we'll check out the vacuum leaks and see if there is anything obvious causing it to idle rough or miss. If you've changed any other ignition parts (plugs, wires, coil packs, insulators, etc), please let us know when you drop it off.
