Well I finally tracked down my miss at 3200. Installed new o2 sensor in a better location but no luck. Going back to basics I ignored what my in-line spark tester said and installed a new coil. Bingo! Seems weird that it tested good and acted good but would drop voltage only at normal engine temps. The only way to actually see the drop is to use an old school engine analyzer (scope). My shops only scope is built into our scanner. Thanks for your help with this. At least now I got a new o2 sensor that reads right without a doubt.

yeah no problem. it actually doesn't route thru the stereo if just disconnects the audio from the stereo and directs the audio from betty via arelay which is internal to betty.

I noticed you touched on this in a previous post, but i was wondering if i could rewire my "betty" voice unit straight from the unit to an extra speaker, instead of it being routed through the stereo? Any thoughts?
