what happens if the knock sensor isnt connected?

98 ls btw stock

 

if ur knock sensor doesnt work its like a 10-15hp loss. i sold a kid a knock sensor on this site a while back and he picked up 12HP on the dyno. bone stock car as well. i have one for sale if you need one. or if its just unconected, connect it

 

would this make my car feel like ****?

 

This will definitely make your car feel like SHITTTT. Vtec wont work either and I think your car will only rev to 5000 rpm. CONNECT IT!!!!!!
