i have a 2005 F150 with 130k miles and its been running funny and from reading all my problems are leading to plugs. i have removed the COPs and i did a quick spray of carb cleaner into the plugs holes but how much am i suppose to spray? im gonna let them soak overnight and give it a try in the AM but i wanna make sure i sprayed enough??? thanks and sorry if its a repeat thread.

When I removed mine I loosened them one half of a rotation, then sprayed until it reached the top of the nut on spark plug.
It's explained somewhere in this video
