I have an A6 block with a Y8 head/intake/tb.
I've had it for about 6 months now and haven't really had any major problems with it.
Ever since the day I fixed the intake manifold leak (where the air assist ports are), it wants to
die after I come to the first couple stops of the day. ( like first stop sign and then first traffic light)
TODAY, it took forever to stop doing that = about 20 minutes of driving.

Any suggestions on what this may be? I haven't checked for codes or anything yet.. and my check engine light isn't on.
thanks

 

bump.. I'm desperate.

 

Maybe when they fixed it they accidently left out one of the vacume lines, causing your bad idle. Maybe who knows.

 

Nah... It was me that fixed it.. I have checked and rechecked and still no idea as to what is causing this.

 

Bump

 

Well, since you're askign for input, I'm having a similar problem.

I looked at my PCV valve and PCV hose .. i'm not sure if this is even in your setup, but my PCV valve was bad, and my PCV hose had a hole in it .. and when I fixed it, some of my idle problems were fixed.

You should just check all the tubing in your car, and piping .. to ensure that there isn't a leak anywhere.

(I'm no expert, and moreover .. i'm still waiting for my similair question to be answereD)
