Change both. I just picked up 2 sensors from a guy in the for sale section for 25 shipped. They were take offs from a crate motor. A lot better than the $40 each new from everywhere else.

the injectors to unplug are the hardest thing really, and be careful trying to unplug the knock sensors the connector is easily brakeable, also you must replace the intake gaskets while there the new updated desgin are green, vs the old orange ones
