Rpm drop when stop the car

[Joseph]

Hi everyone, any know why ? after i changed my air intake
when i come to a stop or even when its on park the RPM’s drop
so much it feels that the car will turn off..it hasnt turned off..but
it feels like it will

er your revs will drop when your at a complete stop from 3-> 1 or less cause thats when its only idling if this is for an auto car would be the same aswell.

That's the problem. You can't use that adaptor...the afm is very sensitive. It needs to be at a certain distance from the intake manifold and the housing must have vanes

That pipe looks like it's designed for the dc5

[Joseph]

But the seller told me for fd2... it's simota pipe...
I wonder where can i buy the housing maf adapter?
Sad ;(

[xenonkuraz]

Can you take a picture of inside the pipe? The maf side
