Hi I have a 2014 Tahoe LTZ. Runs great but last week as I was driving home, when I reached my street I placed it in neutral. The engine surged 2-300 rpm. As I coasted home. No other obvious issues so I went around the block and did it again. Sure enough it surged again. Has anyone experienced this?

Im experiencing surging of 3-450 rpms when in park or neutral. Nothing while in drive or manual. Looking for possible evap and vacuum leaks. Let me know if you ever figured out your issue. Ive cleaned throttle body and maf with no success.

Idle speed maps are different between park/neutral & drive, but the difference is only 75 rpms.

I live on a big hill and use neutral to coast down and mine surges,but in park it does not or when warm. Obviously can't in gear, probably wasting more money letting it idle in neutral lol
