this vital part on one of my cars is not working properly. The idle won´t go below 1500 rpm.

As the name suggests its a cold start valve so when the engine is warm it is not is use. without the filter there is a direct path for any debris to go straight into the cylinders. If you can do without the cold start then just block off the inlet on the plenum until you get the system refurbished or replaced.Thanks to all. Yes, it is the AAV. I just removed the filter and put my finger tip against the tube , and the revs dropped to normal (with hot engine?
how important is the filter? How about replacing it with a wine cork?
