Hello everyone, Iím new to the Volvo world but I have a 04 2.9 t6 giving me fits. I installed a used 100k mile engine into my xc90 after the one I had threw a rod. The engine was a running and driving engine so it should not have any issues. The coolant nipple was broke off so I had to replace the thermostat housing and I removed the vvt housing to get the wire for the temp sensor out. After installing it will start and run and then throw a cel. After I check it and get the 16 and 17 code and clear it it wonít stay running more than 10 seconds....any suggestions, Iíve shorted the battery cables and removed, cleaned the vvt and the timing belt was never removed
