07 Mountaineer P06B Torque Calculation Performance

My wife's told me her mountaineer stalled after starting the other day and later it revved the engine after starting and had a check engine light. Light went out by itself. Checked for stored faults and had a P061B Torque Calculation Performance? Didn't find much on the web. Any ideas?

Sorry for the delay in seeing this. It didn't flag as a new thread for some reason.

Here's what the factory service manual lists for this diagnostic code:

Description: Indicates a calculation error occurred in the powertrain control module (PCM).
Diagnostic Aids: Check for sensor and circuit related DTCs. Do not install a new electronic throttle body (ETB) for this DTC. GO to Pinpoint Test QE (http://www.automotiveforums.com/vbulletin/V72~us~en~file=V725121.htm~gen~ref.htm).

From Pinpoint Test QE:
Note: Diagnose and repair the following DTCs through Section 4, Diagnostic Trouble Code (DTC) Charts and Descriptions (http://www.automotiveforums.com/vbulletin/V72~us~en~file=V724001.htm~gen~ref.htm)and the Workshop Manual respectively before entering this pinpoint test:


P0715
P0720
P0731-P0735
P0102-P0104
P0321
C1165

This pinpoint test is intended to diagnose the informational powertrain control module (PCM) diagnostic trouble codes (DTCs).
The informational DTCs are the result of limited operating strategy (LOS) or failure mode effects management (FMEM) operating strategy that maintains limited vehicle function in the event of a PCM, harness, or component concern.
Circuit DTCs can be accompanied by the informational DTCs, and should be diagnosed first. Informational DTCs without circuit DTCs may or may not indicate the actual concern and should be diagnosed as a symptom.
