Ok, so when i did my MAF conversion, i plugged the line with silicone gasket maker(all i had available). its holding up, but i'm not so sure that i feel safe in the long run. What has everyone else used??? I was told to use a screw, but i'm not sure what size screw.

any help???

 

melt it shut

 

Buy vacuum line caps, that is what I used.

 

you can buy vac line caps at your local auto part store... and make sure you dont have the MAP sensor itself capped off... it has to read atmosphere pressure

 

I just shoved a screw up in mine
