Angry 2 spark plugs wont come out

i tryed to replace my spark plugs but 2 of them wont come out. My car is misfiring pretty bad so i figured new spark plugs will take care of this. However, 2 of them must be seized cuz they wont move at all. Anybody know any good way to get the spark plugs out? Or maybe some fluids/sprays that i can use to let the spark plugs soak maybe?


Thanks

Start the car and let it run to operating temp. Shut it off and let it cool, still warm but not hot. Spray with some PB blaster and let it sit to cool a little longer. Try to work the plug out but don't force it, it'll easily strip, but a little warmth should help. Be careful and don't force it

Try driving your car until its at normal(hot) temperature, then go home and try to take them out. Your car will heat up and the metal of your head will expand a bit letting some small play to pull it out.

Good luck! if it feels its going to brake, stop there and go to garage because if spark plug breaks, you'll have to take off the head.

Same thing happened with my number 3 cylinder. All that carbon buildup caused the plug to sieze. I tried working the plug back and forth for over an hour spraying some anti-sieze liquid everytime and the plug would not move.

I ended up taking it to a machine shop that slowly removed the plug and took half the threads with it. They then did a helicoil on it and installed my new NGK V-powers gapped at 35.

Is that with the head on or off the car? I couldnt find a shop that would do it on the car so I ended up taking the head off and doing my head gasket.

That is with the head on the car. I drove it to their shop, let it cool down for 2 hours (drove on hwy prior), and then they took it in to work on it.
