This is for a b16. Did anything sit between the map sensor and the throttle body? I'm hoping it was a washer or o-ring of some kind 'cause I can hear a lot of hissing activity around the sensor when the car is running, and the idle fluctuates (which is what I'd expect if the MAP sensor is leaky).

Does anyone have a part number for the sealing thing that I'm missing? Or is there a suitable generic (non-OEM) replacement?

Thanks!

 

its just a rubber o-ring you can probly go to petboys or a hardwear store in your area and get one.
