Yeesh...was that all one sentence?

Gonna need to get a scantool on it and grab some data, one session while it's running good and another while it's running bad. If you have access to a laptop you can use Craig Moates' software and an Andrew Mattei cable (Craig is free, Mattei gets $60 or so for a cable) for this.
