One stuck spark plug, in 2006, 60k miles I changed spark plugs for first time in Arizona, in 2017 in Florida at 120k miles i did 2nd at Toyota dealer, one spark plug is stuck,
Should i try to get it out or just leave it? I waited to long to change them

I would squirt a little JB Blaster on it and let it soak a day or so, then try to remove it. A dab of never seize on the plug threads is something I try to always do, just cuz. I did say "try". Memory is so over rated… Chap
