Hey guys I have a 06 d40 4.0l petrol Spain build with 220000kms that was just serviced, I got roughly 50kms out of it before I noticed it was misfiring, checked all the plugs and the 3 on the drivers side were covered in oil, ended up replacing the valve cover, valve cover gaskets, plugs and ignition coils along with the vvt solenoid gasket and intake plenum gaskets and is now running like it’s in limp mode very sluggish any ideas what it might be?
