2011 Chevrolet Cruze - scary sputter at idle

while idling at traffic light it gives a sputter like it is lurching forward, very noticeable scares the crap out of me…please help diagnostic states that nothing is wrong electronically.

Only a hands-on examination by a qualified mechanic could tell you for sure, but this sounds to me like a bad/dirty Idle Air Control (IAC).

The a/c compressor is probably kicking in when this happens.Turn the a/c off and see if it changes anything.

I wonder who or what this diagnostic was done by.
