We know how you feel. Sometimes you just want to lock your toolbox and head for home. Diagnosing a Power Stroke Diesel can sometimes test the patience of the best technicians and with all of the superseded TSB's and updated procedures that seem to be forever changing, who can keep up? Let us take the guesswork out of the job for you. Close your eyes and think with deep concentration about the engine and condition you are diagnosing then click the button for your magic diagnosis.

Apparently we do have a sense of humor! This diagnostic aid is dedicated to Lorenzo who inspired it's conception. This is intended to provide entertainment only and should not be used for actual diagnosis. Any indicated diagnosis that matches any successful diagnosis and repair is purely coincidental though we admit this tool may be more accurate. Always consult the workshop manual and for God's sake wear safety glasses!
