Hey guys whenever my car is at idle I look at my rpm gauge and the meter usually twitches up and down very little instead of just sitting still not moving at all its kind of moves up and down very little u cant tell unless u stare at it. Is this normal..??

 

normal

 

Yea it's normal, I think all Z's do that. I hear a grounding kit will 'stabilize' your RPM while idle.

 

any grounding kits

 

Yeah, Lots of people say grounding kits aren't worth anything. But, I installed mine and the idles is smooth now. It used to feel like it was missing all the time at idle.
I first noticed it when I was looking at a map in the car with the motor on. After the grounding kit..... smooth as can be.

 

k good thanks guys
