If the fuel trim is not right it will throw a o2 code just tha same as a missfire in most cars. try moveing timeing back one tooth before going out and replacing it. make sure u run it for a while then pull tha negitive battery cable off for ten or more seconds to reset the ecu.

you need to have the belt that matches whatever head you put on the car NO MATTER WHAT. fix that, then diagnose your other issues.
