What check valve are you referring to?

i am talking about the linkses check valve that go's on top of the throtle boddy,

how do you attach picture? so i could show you how the check valve looks like

Is the check engine light on? Is the interface box flashing or solid? If you can datalog are there any error codes?

More info is needed.

hmmm.. there is no check engine light, can't datalog, was not enable when bought it, though i believe i bought it with that mod enable. have to go back and ask the guy that i bought it from. the box sometime is flashing and sometime it stays on.

thanks
