Car stutters when initially accelerating

Well? Was able to get the front 3 plugs out… Took a breaker bar, a lot of nervous sweat, penetrating fluid, and patience back and forth… There was hardly any electrode left on them. Must be the originals? 200,000 miles. Anyways, no more stuttering. I will get the back 3 sometime soon. Have to take the intake off to get to them. Put anti-sieze on the new ones.

Thanks for your help
