my knock sensor is broken. the top of the knock sensor broke off and the bottom part that screws in is stuck so that there is no way to get it out . is there anyway that it can be taken out? is it true that if you dont have a knock sensor your car wont run at 100%? any help will be apreciated.

 

you can drill it out an d put a new 1 in. knock sensors retard timing when it detects pinging
