Why does my Nissan 370Z engine keep sputtering while idling?

I recently noticed that my Nissan 370Z's engine seems to sputter and stutter while idling. This never used to happen before and it's quite concerning. Could it be a sign of a bigger issue? What could be causing this and what steps should I take to fix it?

It's important to get your engine checked by a mechanic as soon as possible. Sputtering while idling could be a sign of a variety of issues, such as a clogged fuel filter, spark plugs that need to be replaced, or a problem with the air intake system.

Have you noticed any other symptoms besides the sputtering? It could also be a problem with the exhaust system, such as a leak or a faulty oxygen sensor. It's best to have a professional diagnose the issue and make necessary repairs.
