All of a sudden, my car when sitting idle is starting to sputter. Trying to describe it, it feels like the engine is jerking in spurts. Once I accelerate, it drives fine, but when it comes to a stop, it sputters again. It does it quite often, but sometimes it will sit smooth at idle.

I just had the 135k mile service and my oil pan gasket replaced for a leak.

Did they screw something up? The work was done at the delearship.

Thanks. Any and all suggestions are appreciated.
