hey guys i just hit 1000 miles on my Z and whenever im idling i notice my car start shaking a bit and my rpm doesnt stay steady... anyone know what could be wrong ? or is this normal for the Z ? thanks for da help in advance

 

your gonna get told to get a grounding kit. it might help, I didnt have it to start with so I donno. i noticed no difference, but I didnt have a problem.

 

How much is it moving? Maybe you only have 1k miles. Let it breakin more miles and see what happens. I have over 14k miles and the rpm doesnt move a bit at idle.

 

my rpm goes up n down at about 100 rpm's the most its never gone up till 1,000 RPM's but its noticeable... my shift **** also shakes a lot and whenever the rpm plays around u can feel it... seems like engine is having trouble or somethin i dunno... should i change my oil soon? because my oil is getting dirty anyways

 

could, but I doubt that has anything to do with it. the shifter does vibrate, thats normal.

has anything happened to it? does it ALWAYS vary RPMs at idle or just sometimes, how often?

 

RPMs always vary at idle yes.... u think i should just take it in 2 da dealer have em take a look ?

 

I hope you use premium gas..

 

This engine has enough cam for a little lope at idle, the needle shouldn't move around much though.

 

haha yeah... ive been using premium fuel from day one... maybe the dealer put something less than premium and thats the reason ?

 

I get the same irregular idle at times. Happens when stopped at lights, etc. after the car has warmed up. Has never come close to stalling, but the RPM's do dip enough to be noticeable.

I have installed a grounding kit, and it did seem to reduce the frequency of this. I wonder if it is an issue with "bad" gas. My Honda CRX used to do the same thing though. I just hate bringing my car into the dealer, almost guaranteed I will notice something wrong (new scratch or chip or something) when I get it back...

my dad's Z still does this even with a grounding kit.

 

yea mine does too... but i don't have a grounding kit (yet)

 

Mine seemed to be perfect after grounding kit. I only started to notice slight fluctuation and lower occasional idle after my intake was installed. Not saying it wasnt before the intake, just i notced it after intake.

 

is your ac on when you turn on your car? If so, it should rattle or jiggle for a little bit. If you turn your ac off, the rpm should drop a little. Try it out man.
