I do not recall the numbers for the battery. I visited the dealer parts department and the parts.. MarcW - Thursday, 2 June, 2011, at 3:30:15 pm |

All very good points, and thank you for the reply!
Do you know those numbers for the new battery you got? The AH and CCA #s. I may be wrong, but I can't imagine them being unique to Porsche's battery.
I don't know a thing about the throttle bodies condition. I was planning on cleaning it when I replaced my AOS (I have leaking on the crank case and I suspect the AOS which I believe is original from 2000).
As far as I can tell, the engine sounds fine, but then again, I have a GHL on the back that is pretty loud over the engine noise so it's kinda hard to be certain.
I have done 100% of the electrical work on my car.
The radio is stock, I simply added the 220 OEM AUX (phone) kit and utilized the switched power function from that as well. I never messed with the dash elsewhere.
I don't think it's the HIDs or the radio add-ons. The reason I don't is that when I have the radio, XM, audio-bypass, and HIDs turned off, the bouncing of the RPMs at idle is the same.
Sometimes (well, I've noticed it a lot lately) when I start my car, the RPMs at idle will be around or over 1k, max I think I've seen is maybe 1,200. After the car is warmed up and I stop at a red light, for example, the RPMs will be around maybe 650-800. The bouncing is very minimal, not like a lot of the drastic bouncing other people talk about where it moves around or over 1000 RPM. It will maybe oscillate between 75 RPM down from center 75 RPM up from center (visually).
Since you bring up the radio, I would like to find a way to ground things a bit better. I really don't think this is the issue, but I'll mention it as fodder if you guys think it might be a cause. When I have the radio volume up and my RPMs are up, I can hear the whirling of the RPMs interfering with the audio signal. I currently have 2 ground loop isolators (radio shack): one for the XM and one for the secondary AUX which the bypass auto-detects when audio is played.
Thanks again for the input, MarcW!

Why do you think that is??? I have them "unlisted" on youtube, but I'm pretty sure you can still view a direct link.
Very strange.
Can anyone else not see the videos?
Thanks for the AOS tip. I wonder if this and a dirty throttle body could be contributing to my RPM/tacho issues.
I'll likely order and AOS this week. Confirm for me, please, it's been a while since I reviewed the DIY on Pedro's site and I'm exhausted..., can I access and do this from above, or do I need to get under or remove the rear right wheel. I'm looking to avoid lifting the car at this time...
Thanks again!
