picked up a 2014 with 11.5k miles couple months back, while it drives fine, my idle almost feels like its missing, like an inconsistent fire. my guess is plugs seeing how rusty the manifolds got over the years, but would it be cost effective to pick up a plug and pack tune up kit and do it all together or just plugs?

idle settles around 500, but once or twice on rotation itll dip do about 400 but go back up..
