The trouble code you got was: "P061B Internal Control Module Torque Calculation Performance", which is helpful as hell, isn't it?

I can't believe your customized settings had anything to do with this.

Ah dear, I see I'm a day late and a dollar short again, Bill's already on it. I should have thought of corrupted files. But, of greater interest to me now, is why are files becoming corrupted now and then?

Even worse, now that I read a few posts back, I see this DTC is a definite symptom. I must be losing it!

Yes, normal temperature range. No big loads or towing. Just going from work to McDee's at lunch.

Agreed, this DTC looks like it might pop up every once in a great while. Might just be a 4.6 problem, also.

Thanks.
