Stripped Pan Head Screw - Cylinder #6

If that is a coil - then that should be a torx screw!
Sometimes an allen wrench will undo a stripped torx screw.

Drill the head off, pull the coil off and then there should be no pressure on the screw to come out with your mole grips.

Cut a slot into with a Dremel and use a regular screwdriver turned with vice grips.

It should be an Allen/hex, not Torx.

An Irwin (or equivalent) bolt extractor should also work for that. Then replace the bolt when reinstalling the coil.

Looks like you have decent contact on there with the vice grips... How torqued down are those screws? If you can get a 1/4 of a turn on there and break the tension, rinse and repeat that step one or two more times, you might be able to then simply back it out by hand. I had a similar situation with a cam-shaft position sensor on my BMW a few years back and the aforementioned process did the trick.

Good Luck!
