HELLPP! P0021 , misfiring p0300 codes
So I have never posted on here and am desperate for some feedback or advice before hauling to Mercedes dealership I have a 2010 c300 the car was running fine daily till the other morning I woke up and it started misfiring and would barely accelerate so I had the car scanned and got the p0021 code and the misfiring p0300 code along with missfiring of cylinder 5 & 4 so I got new plugs and and new camshaft position sensors... still misfiring.. so I just orderd camshalf adjuster solinoids in hopes that will help. I'm also gonna drain oil and change filter and oil tomorow has anyone had this problem or have any ideas on what it could be any fees back would appreciated
