whats up with 80 mph on this car. currently have a crankshaft sensor error CEL when i go past 80mph. just shuts off. im clueless on that but itll have to wait as tomorrow ill be drilling. that is if i can beat the rain & i'll deal with the humidity. (central Florida)

Question: can i take the main electrical harness off after ive drilled???? that baby doesnt wanna budge.......

Also, if u drill a little bit of the area around the pin, will the ignition be floppy once i put it all back together???? Thanks in advance.
