I just got round to installing a new AOS. The install went quickly and easily. I used the right tool to remove the spring clamps. I installed a new tube that feeds the throttle body rather than clean the oil out of the old one. The coolest thing about the process was using the new spring clamp for the lower bellows. I bought all of the parts from Pelican including a new spring clamp. Installation of the new spring clamp was the coolest part. It had a blue clip on it that holds it open. Slide the bellows with the spring clamp in place. Pull the blue clip and the clamp closes. No messing with pliers to set the clamp - almost eliminating the chance to tear the bellows or set it out of place. Literally it only took a moment to install that bellows. That is not something mentioned in any of info I read on the installation and was the best $2.25 I might have ever spent for a Porsche part.

I did not yet run any additional diagnostics to determine if the problem has resolved.
