Hi Everyone,

Hoping for some direction or ideas. 2006 Cayenne Turbo S. Finished reinstalling the intake and all vacuum lines, ETC. Started the Cayenne and it runs for the first 10 seconds or so. Then it begins to idle down, running very roughly until it basically dies. You can keep starting it over and over, it will run fine for 10 seconds then starts to stumble. Rinse and repeat!

During the first 10 seconds or so, you can press the throttle and it will rev (roughly), but then it once it starts to stumble, no matter how much you press the throttle it will not rev. I am open to ideas!!
Thanks in advance to all the Rennlist Guru's!!! Oh and I will post a video on Saturday so you can hear it.

Did you plug the camshaft position sensors back in?

They were never unplugged. I still come back to a vacuum issue. Trying to arrange for a smoke machine to test for leaks.

i used a paint can, some tubing, compressor and very low psi and incense. Sounds crazy but it made a ton of smoke and worked great. Cost $20ish in lowes stuff.
