Rough idle and no vacume?

I would have someone else who knows what they are looking at check your timing marks and then use a timing light to set the base timing. Also 94talon with a CAS sensor on a mitsu the ignition timing will drift as much as 1 deg advanced or retard from what you set it to, just from the play in the timing belt and from the CAS to cam connection.
