Loving the DSM, few minor problems

[Junkyardspecial]

So I ended up purchasing a moderately modded 1G Talon TSI, as some of you saw in a previous thread of mine. The car runs like a top, Is in great condition all around but I have two minor problems I notice which I would like to fix. It seems like it has a problem with the idle control valve, if this car has one.

Problem: When I clutch out to coast or stop, the car will try to stall or bog down 500rpm and bounce back to idle then back down to 500rpm. When the AC is on, it will stall, and idles kind of rough. Could that be an AC compressor clutch problem? Normally it idles at 900-1250.

Thanks for the help!

Add mods to your profile so we can better assist you in diagnosing problems..Sounds like idle surge to me..But I cold be wrong..

Also when you push in the clutch the car could bog because the bov is not recuirculated..

You can adjust the idle, there is a screw on the front of the trottle body..Back it out a bit and the idle will go up, Down and the idle drops..

It wouldnt let me add mods to my profile since I am new. Its a big 16g turbo with a recirculated Greddy type s BOV. Apexi safc with tune, 500cc injectors,Hallman mbc. I appreciate the help, I will try adjusting the screw, that was my first idea of a fix anyway.

I was just reading that! My symptoms seem similar to that, but I wonder if that would cause rough idle with ac compressor on as well.
