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.

Do you
have the same problem?

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.
