my first question is what are the two sensors called that have the arrows pointed at them, and should i replace them before i put my manifold on my new bottom half? the second question is for the last couple of days i have been trying to take this piece off with no success. i have been spraying it with WD40 for a few days and it won't budge. i don't wanna break it but i wanna paint the manifold so it would be nice to take it off for that.
