Recently I noticed that on cold start ups my ‘13 Tahoe rpms will jump to 1800-2000 and fall back down to around 600-700 after a few seconds, is this normal?
Once it’s warmed up it only jumps to about 1500-1600 on start up then settles after a few seconds.
I’ve also noticed when i’m sitting at a stop light it almost feels like a very slight vibration but I don’t see the rpms move at all. Any help is appreciated. TIA
