Need help with check engine light :/
The car is an 05 m271 with 66k on it and im sure no one has ever changed the stock plugs.. I think all recalls are done on it.. The car idles kind of rough right now and the idles keeps fluctuating around 1000 rpm and below like im revving the engine a bit while im not..
so what do you guys think should the spark plugs take care of this? thx

P0302 & P0304 = misfires on cylinders 2 & 4
Check - Plugs, wires & coilpacks. When last did this car have a new fuel filter?
