2010 2ss

Intermittent shudder (very slight) at idle. No rpm fluctuations, engine runs great ! visual inspection...everything looks good. Can't hear or feel anything under the hood, only in the seat. Hope its not a stupid afm lifter issue. 39,900 miles. appreciate any thoughts. Thanks in advance.

You have a 2010 automatic? Never knew those had AFM or DFM options installed.

Maybe check the intake sensor, might be dirty or clean the throttle body. I'm confident you wasted your money on the AFM module. Make sure to always run premium fuel.
