Hey ive been trying to remove the map sensor for something but i cant remove the screw above it. I cant heat it with a torch or it would burn the sensor. Ive been spraying pb blaster (penetrating oil) for about 3 days and its still stuck. The screw is also starting to get stripped. I thought about buying this impact screwdriver but im not sure if it has the correct size for such a small screw. Can you guys recommend any other alternatives? Thx !

 

If you have a dermal, cut lengthwise across the screw deep enough to fit a large flat head screwdriver and give it the beans. Afterward, buy new appropriate sized phillips head at hardware store if desired.

 

use a small hammer and TAP (yes TAP not hammer the shit out of it) on top of the screw driver and slowly turn the screw driver.

 

Get a big screw driver with more leverge, you'll be surprised how something as basic as a screw driver can help. If that fails, grab some vise grips (and new screws) as that never fails. Vise grips are my go to for rounded bits.
