ok so im replacing the iacv on my car and noticed the gasket had some sections that where scored for removal but where not removed but it still has an opening on the butterfly section of the throttle body and the trace leads up to the map sensor i think ,.......so do i need to remove the remaining parts of the gasket or is it ok with the amount of opening at the end of the trace ???

 

ok here is the pics

 

You need to remove all of the old gasket to leave a flat surface for the new gasket to seal on. It's not "scored for removal"-- it is supposed to be one piece.

 

got it thanks
