So my car has a small vibration when it's idling. It also seams to stutter sometimes when I step on the gas. I put fuel cleaner in my last tank of gas and I have carb. Cleaner just in case. But im not sure where it's located. Also I noticed that the belt seams alittle loud and it vibrates the whole engine which is vibrating my car. Not bad but nociable. Any help would be appreciated.
