i got a engine vibration at idle. it vibrates when the engine is hot and cold. the rpm goes from around 900 to 1k and it goes back and forth. i first thought it was the spark plugs and thats why its misfiring so i changed them. Apparently thats not the issue. So I dont know what else it could be and i need HELP!

Motor mounts for sure.

 

If I had a dollar for every vibration thread.... I'd have at least an R3.
