2007 E350 code 1200/1208 (B/S has been replaced)
My mothers 2007 E350 has had the balance shaft replaced by the dealer about 5 years ago. The vehicle is now throwing codes 1200 and 1208 or P0016 and P0017. Vehicle is sluggish at low RPM and seems to burn quite a bit of oil however I'm assuming that is a unrelated problem. Any ideas what could be wrong? Cam adjusters?
Here are some pics I took of cam timing at 305*
