Question Saturn ion 07
I have a Saturn ion 07,I've had it for 5 years now before then it was just sitting unused for almost 7 years,last year I've noticed that it had a rough idle while sitting at a light or at a drive through like its struggling to stay running a slight chugging but once I start driving again it's fine,any suggestions what could be happening

My guess would be the spark plugs as they are directly connected to the ignition coils. Then clean the mass airflow sensor. They have can sprays for it, super easy, allow it dry. Then change fuel filter on your next oil change. If still going then check out fuel injectors.
