Possible misfire or just needs good tune up?

Hello,
I am looking at a 1993 Nissan Sentra SE 1.6L with 149K miles.
I test drove her yesterday but she was idling real rough. Feels like its missing on a cylinder. Weird part is after 2k rpms it smooths out and stays smooth all the way up. I dont want to purchase this if its going to be a big issue. Vaccum leak? good tune up? No CEL by the way.

Most probably the idling speed is too low and that is usually due to a dirty idle control air passages. Cleaning the throttle body and IAC should solve the problem.
