Have any aftermarket parts installed??????
I know thats probably not your issue, but it can happen.
I'd like to see whatever info you can send, IF I AM ABLE TO VIEW IT.

The aftermarket stuff that I have includes:
- S&S headers
- Cap that's been on since day one
- USA Spec aux input adapter that's plugged into the back of the head unit
- XM satellite radio tuner that draws power from the head unit power leads
I think that you need the Auterra application to replay its data files but I'm not sure of that. At the very least I can take screen shots of the line graphs which would give you a pretty good idea of what's going on, especially if I zoomed in on any part of the graphs. The screen shots are saved as JPEG files that I can then send to you.
