i have a 96 neon sport and when the car is not moving but is in gear, its an auto tranny, there is a lot of rumble, the type that is typical on a 4 cylinder car, i'm just trying to figure out what could cause this so i can smooth it out a little bit. i would guess preliminarily that we are talking about an oxygen sensor and plugs and wires, but what have other people found out about these? thanks for the input.

 

i would guess shot engine mounts causing too much vibration. but it took me 3 times to re-read your post for it to make sence.

 

^^^ thats kinda funny
