RX8 dies on idle. Can this be caused by a dirty air box, filter, intake?
 

Hey guys, my 8 is having rough idle and sometimes dies when slowing down. I opened the air box and first thing I noticed is oil on the filter. After that I found leaves in the airbox and it is really dirty. Can the rough idle and car dying be fixed with a tune up? I bought the car in July 2015 and has never been into any tune up or anything like that. I thought of changing plugs, wires, and coils but I dont think wires is necessary since I just found out its has NGK plug wires. I am still changing coils and spark plugs just in case, as well as all filters and oil change. Do you think this will fix my issues?
