alrite, i tried using the search and it keeps telling me the search is temporarily unavailable. well, i just tried installing a missing link into my friends car and when start it up, the idle is hella low with the needle jumping up and down, then it eventually dies out. we tried it on my friends other car with the same missing link, same result. does anyone know why the missing link does that? thanks in advance.

 

you may have it up side down. there is only one way to install it. it is a one way check valve.
