well i tired to install my missing link on my h22 turbo. i had the check valves running though it. after i got it installed it started to blink a cel, so i stop right a way thinking i am misfiring. got it home and took off the missing link and check my plugs to see if i was misfiring. well the plugs are fine and i put my map sensor back on without the check valves back on, which i forgot to put back on. took it for a test drive and no cel came on at all? so what gives, do i need the check valves on or can i leave them off? thanks

 

Umm.. How about a little more info about your setup.. What fuel management do you have?? A check valve by itself isnt going to add fuel..
