Re: some issues (kj217)

Sounds like one of your hoses is loose/has a leak...

Re: some issues (kj217)

Anything is possible.<p>What kind of FMIC? W/ my phMIC, the clamp that attached to the plastic pipe leading to the TB crimped it, so even though it looked fine and was tight, the crimp caused a pretty substantial leak.

If everything is installed correctly, it should run as it did before (only a bit faster)!

Re: (zabto)

...but at IDLE? I know it's a closed system and the released air is supposed to be vented back into the system post MAF, but this shouldn't make a difference at idle, as you are not venting any measured air to the atmosphere at that time.<p>It would cause the car to run *rich* if anything, no?<p>*edit* Just saw the OP's mention of running 'rich' w/ the cat removed... <IMG NAME="icon" SRC="http://www.vwvortex.com/zeroforum_graphics/screwy.gif" BORDER="0">

Your BOV<p>Is it an HKS LOOK ALIKE BOV?<p>Is the vaccum line tapped in the right place?<p>Is it stuck open?<p>If YES to any of thoes issues....that may cause a problem at idle, and driving.
