Well I just changed my throttle body gasket and now it seems like it has a little leak somewhere but I cant seem to find it. When I start up the car is idles around 1500 then after 3 - 5 secs it drops to normal. Then you cant hear the leak no more, but once I shut down the car you hear the leak. Any ideas?

 

Well, if you haven't changed anything other than the TB gasket, then either you got the wrong one or didn't tighten it up good enough.

Well the weird thing is that I went threw 3 throttle body and they still act the same way but only one of them would be fine. The only one that didnt have the leak was one with out the fuel evap.

From the looks of the one that didnt leak it doesnt have an extra hole inside the circle of the throttle body.

The old tb I had on my car didnt have a fuel evap on there to plug in so I had to change tb for state reff. So I went through 3 tb and it still has a vacuum leak around the same spot.

 

Was it a swap, or was it stock?
