September 9, 2006Volvo, did you ever get the matter resolved? I remember the same thing happened to my F-150 a few years back. I too did not disconnect the negative battery terminal. I had to have the dealer reset it, then I installed it but disconnected the battery the second time and no more issues.
Just out of curiosity, are you finding that you now have to use Premium Unleaded to get rid of the knocking? I installed a Airaid system on my Yukon and then ended up returning it because of the knocking. Now days I just drop in a K&N Filter and call it a day.
