Engine missing at idle

I recently picked up a 2001 A4 1.8T. After the car warms up it tends to "missfire" while idling at a stoplight. Any ideas? I did a search of the forum but didn't find anything relevant.

Pull the codes. could be anything from a bad spark plug to a vacuum leak.

Could need a throttle body alignment.

if the check engine light on, then pull the code from autozone or advance auto parts. they will do it for free. while you are there get yourself a new set of plugs NGK BKR6E.
