Hey guys so recently my car started vibrating. It's weird because I can hear it more than I can feel it. I also feel like it's stronger once put in gear (reverse or drive) the car has new ac delco spark plugs, new wires all 4 new ignition coils, what could be causing the vibration? A motor mount? I haven't ran the codes just yet but I did so a while ago and I don't really remember seeing anything that would be the cause of this. Any help please? I'm just really trying to get this car to the best shape I can get it and the vibrating is annoying and kind of embarrassing (lol)

I believe you might be confusing the "audience" with your terminology -
VIBRATING usually refers to rolling-related problems -
out of balance tires - bent wheels - etc -
and judging by your description - that is NOT it -
if your "vibration" is happening at idle -
you have a misfire -
what can cause it? -
vacuum leaks - dirty throttle body -
defective new parts - LOTS of things -
Sorry guys. Well to me it feels like it's vibrating, it only happens at idle. When I'm in park it happens also when I'm waiting at a red light or something. I checked the codes and there is no misfire code which is P0300 right? or something like that. Anyways also I didn't do the coils,wires,plugs myself so I'm not sure, but I mean when they were first done the car ran so smooth it was amazing and now all of a sudden this is happening.
