but yeah I always put spray fluid on the bolts that seem full of rust but thank you for the advice



Sounds like the DPFE sensor to me.
No need to remove the EGR valve for you.

Using an easy out or similar tool would be my choice.
Runing with only 1 bolt holding it on isn't my first choice. Expect problems later.
2 bolts were put there for a reason.
