Default 2003 Tahoe 5.7l little connector just under the top plastic engine cover rh

Can someone tell me what the connector is that is located undr the plastic engine cover on the right hand side? I get reduced engine power signal often and when I squirt WD40 on the connector the power returns. Maybe a solution to this problem.

Is it an electrical connector, or a hose connector? Post a picture. What are you calling right side? Passenger side or driver side?

Maybe if you put a little effort into your question we will put a little effort into responding.
