Hello. Welcome to Just Answer. Please allow me to assist you. The back plugs are very difficult to replace. In the shop, we find that by removing the intake plenum, the rear plugs are very easy to get to. This sounds like a lot of work, but, compared to trying to get the rear plugs out without pulling the intake, the time is actually cut in half. Remember to use new intake manifold gaskets when you pull the plenum.

Do you have any instruction on how to remove the intake plenum?
Toyota Mechanic: Toyota Service, Toyota Expert replied 2 years ago

Remove the battery, the air filter box and the intake tube. Remove the 4 bolts from the throttle body and let it hang. Remove all of the intake manifold bots and pull it off. Use new intake manifold gaskets and a new throttle body gasket.
