C6 surging
My 2006 C6 Corvette (LS2, base model) has an idle surge. It doesn’t happen all the time. I’ve already replaced the spark plugs and installed a new MAF sensor, but the issue is still present. Has anyone experienced something similar or have any ideas on what I should check next?

I'm sure there have been a hundred members on here that have had the same thing...what fixed theirs may not fix yours !!...do you have a scan tool ??...are you sure your new MAF sensor is good ??...because it's new doesn't mean it's good...you test the MAF wiring ??...if there is a wiring issue 100 new MAF sensors won't fix it...if you just want to "check" or in other words replace some parts you can replace the MAP sensor...you may have a vacuum leak or incorrect fuel pressure...instead of guessing and replacing parts find an auto diagnostician in your area.
