i was using the check valves and now i have the missing link...when i drive my check engine lite still comes on sometimes under boost...not sure if it's because i still have the check valves on the car or if i did the missing link wrong (kinda hard to put that in wrong)...help me out...1

 

Well is it a map sensor code?
You might as well get those check valves out of there. Any leaks around the missing link?

 

I dont have the instructions on the missing link, but i remember something about using vaseline if it fails, hmm try searching, i know this was covered. Good luck though, i had no problems when i had the missing link, nor did i need check valves.

 

What? you have check valves and the missing link? Where did you put the check valves? Dude get rid of the check valves if you have the missing link. Got a picture of your set up? With the missing link in? And what was the code from the computer?
