Need to regroup with a plan to address the stubborn plug(s).
Spray your plugs with a good penetrating oil and let them sit over night. Clean out the area around them and spray them again.
When you go to remove them, turn the wrench to try to loosen it, if it doesn't move turn the wrench to tighten them a little. Don't over do it. Then loosen, tighten. Spray again, repeat.
