CEL Code / Code C230 kompressor 1999 / Oil in Air Intake Box
Second is P0304 Code - Cylinder #4 Misfire, So I'm guessing bad spark plug(s)?? I changed them not more than 2012 1 year ago with new 2 new COILS as well which were expensive as well. So Before I do anything, I'd ask for some help, and for others in the future as well, and can CODE P0304 misfire cause a P0170?? in any connection???
BTW I have been getting oil in intake box and leaking a little bit of coolant back of engine, my head gaskets are likely highly leaking, so planning a Engine re-build in the near future for sur but want to make it driveable until then.
