Sometimes when I turn on my Z, the rpm shoots up to 1500, and its never gone that high before. It kinda scared me at first, but now Im just worried. It usually starts up at 1250 or 1300. Also while idling at a red light the Z sometimes shakes as the rpm needle stays steady for a little bit....then dips down a few hundred rpm...then goes back up to normal, with or without AC.

Should I take it in to the dealer? Or are there any easy solutions?

Thanks

I think it's normal, mine starts up around 1500 or a bit higher when colder

 

mine always revs higher and does not come down until the engine gets warm. i think you are just noticing it now and being a little paranoid. its normal

 

paranoid Z owners?! no way man...hahaha yeah i think your right then. i just worry about my baby sometimes... =)

 

vacuum like perhaps?

 

100% normal
