It is having what feels like a misfire and it is idling really rough.
What is your question?
It has also started dropping down to 1k rpm and occassionally dies when pressure is taken of engine (such as pushing in the clutch) which is making it a pain to drive. I just purchased the car a month ago, it started with the rough idle 2 weeks ago and stalling 3 days ago. It has no cel and dealership originally said they seen nothing wrong, other than a emissions recall (which they did). I am lost. I have changed the plugs, wires, looked to a vacuum leak, even had a friend put a scan tool on it and found nothing.

You would imagine it should have set a check engine light if it has such a drivability problem. It's so difficult to guess without being able to experience the problem first hand and at least do some basic diagnostic tests. A professional grade scan tool reads stored trouble codes, pending trouble codes, looks at live sensor data so you can look at a sensors performance and output signals without having to do intensive testing at each sensor, (cheaper scan tools have limited capabilities and may only read the trouble code stored). As with most things automotive it's best to check the basics first, check for vacuum leaks, fuel pressure and delivery volume. Verify engine mechanical integrity before looking for complex problems check that the basics are sound. A more advanced scan tool can look t live sensor data and Mode 6 data that may catch marginal sensors that have not yet set a code. Surprised the dealer wasn't more helpful in solving the problem.
