hey guys, i was doing some work on my EVAP system, when I noticed the small 1/8in synflex air line to the 2 air pistons in front of intake manifold which I believe are for the intake flap inside the manifold was broken. I replaced the line. Also noticed at the T in same line the other end which goes into something behind the drivers side headlight was also broken, so i replaced it as well. however the intake flap still does not work. when I rev up engine nothing happens. on Videos i have seen, when engine starts the pistons move and rotate the flap. when you step on throttle above 4.5RPM the flap rotates other way. mine does not do anything. I have no CEL or any active codes. how can I fix this? i believe this is reason why my car feels very very slow.
