There may be a thread on this already but i didn't have time to look, but why when i am at a total stop, in nuteral, does it feel like the car is idk, bouncing or hopping or shaking or trying to move? i don't even know if that describes it. it just feels like someone is shaking my car ever so slightly. maybe its just me, maybe im on crack or something but does anyone else have this problem? Oh and as far as i can tell, it isn't cross traffic thats doing it.

 

did u buy a pre-modded cobalt?

 

Tranny or Motor mounts would cause it...(stiffer non OEM)

 

thts exactly wht i was thinking

 

mounts are stock, infact i have my aftermarket ones sitting on my dresser, i am well aware that i will feel the shake afterward, and no i don't have a pre modded balt!

and its not really a vibration, it feels kind of like cross traffic would, when a car drives by your car the car usually shakes side to side, but mine feels like it is front to back or something. its really wierd!

 

Is this with the A/C on or off?

 

off!

 

Someone locked in the trunk?

 

lol,not that im aware of!

 

Mine does it too, it's just all the heavy parts in the engine turning. The balance shafts don't take care of everything. My dad's 5.7 GTO does the same thing but way worse. It's more pronounced when the car is colder, right?

 

i actually havn't payed attention to hot or cold, but i will, thanks

 

Mine does this too.. 3 weeks into owning it from brand new off the lot i noticed it. So annoying.. took it to my dealership and they said nothing is wrong, but turned my rotors anyways, for whatever reason -retards.

 

I dunno if you're thinking of the little shake every so often like the car just got the chills? I think it's a typical vibration every so often. My moms Z24 would do it too.

 

good, as long as im not going crazy, thanks guys!

 

Ok I Found Out What It Was, After I Installed My Air Fuel Ratio Gauge I Noticed That After You Take The Car Out Of Gear And Come To A Stop, The Car Starts Running Really Lean And Starts To Miss, It Does This For About 5 Seconds Or So, I Don't Know Why But At Least I Now Know What It Is!!!!
