Hey guys. I have a 99 v6 quattro
my car is not staying steady at idle and when i rev it up and let off the gas it goes down to around 100 rpm or sometimes it even shuts off
I was wondering what this could be.... bad maf?

thanks

 

i dont really know much bout cars but i had a a issue like this and it turned out to be a cracked hose that came off of the air pump. alls i can say is maybe check your hoses. please dont flame me..

 

i just replaced all of the vacuum lines and it still does it. it seems normal when the choke is on, but as soon as the choke turns off it starts to do it when i rev it
