They (2ea.)are in the intake. The intake manifold will need to be removed to get to them. The wire harness and intake manifold gasket should both be replaced when reassembling.
It should take about an hour to change the intake manifold gasket. This part can be replaced by taking off the intake manifold cover, cleaning the old gasket off and sealing a new gasket in the space and tightening the bolts.

take it to a mechanic
