So as of late I have noticed my idle (my rpm gauge) jumping when I am at a stop light, especially when the car is cold, but it will even do it when it is warm. I think this is fairly new because I would have noticed this if it was occurring in the past.

I know my car is under warranty and I can just take it in, but I was trying to see if anyone here has noticed the same thing.

It will be resting at lets say 700 rpm and then have this weird flutter.

I will run down to the car shortly and take a video and post it up to youtube so you guys can see what I am talking about.

 

Here is a quick video

 

Lol it looks like the needle is dancing with the music. I haven't seen that but you should bring it to the dealer and show that video in case it doesn't do it when the dealer has it.

 

Take it in. Mine does not do that either. I have 9800 miles on mine.

 

Could be a defective gauge, honestly. Only way to tell for sure is the dealer will hook to to a scan tool and see if the engine is actually changing RPM while the gauge is bouncing a little.
