My car has been sitting for a decade and I am doing my first plenum pull. I'm definitely not a mechanic but am enjoying getting my hands dirty. The upper plenum is off exposing the injectors, however, you can tell there is a bit of corrosion and rust on everything. I tried my best not to strip any of the injector screws but even after PB Blaster they wouldn't budge and a few screws are stripped. What is the best way for me to try to remove these screws? Should I use a screw extractor or is there a better way?
