I noticed over the past two weeks the needle on the rpms has been teetering when in operation and idling. While driving usually 30 mph+ there is also what seems to be sputtering or a shaking of some sort with the engine while the rpm needle is still teetering. Please help me diagnose this.I haven't done anything with it yet.

Thanks

Hi zoverbey,

Thank you for the donation.

The information provided is rather vague so we can only make a calculated guess for now.

Looks like you have a misfiring in one or more of the cylinders and I would suggest checking the spark plugs and related parts for a start.
