I can't figure out what I did, but my '97 7.3L F250 has had inconsistant but major problems (dying in intersections, crossing highways, etc.) ever since I cleaned out the fuel bowl and removed the corroded heater plate, and replaced the filter, etc. a month ago.

I have read so many positive things about AutoEnginuity's Scan Tool, that I bought the Ford Enhanced version, thinking this would help point me in the right direction.

I think it's installed correctly, I activated the Enhanced Ford upgrade, but I need some help.

Under Vehicle Selection, I have it set to:
Ford - 1997 - Powerstroke 7.3L - Enhanced Powertrain. (I think that's correct.)
When I go to retrive DTC's (diagnostic trouble codes), I'm not sure whether to try All, current system & OBD-II, or no systems. (I've tried all three options.)
The truck dies when It reaches a certain point in the scan (Is that normal?)

No matter what I do, Scantool does NOT return any DTC's. (Is that because our rigs are not OBD-II compliant, or am I doing something wrong?)

The only thing I see is Under Actuation, Command Name it reads "Coast Clutch Solenoid" and under Commanded it reads "Off".
