Ehhhhmmmm.

41 Cylinder Select Error (Faulty or Incorrect Mem-Cal)

Mem-Cal is the PROM that controls the PCM/ECM.
Trouble Code 41 indicates an incorrect MEM-CAL has been installed or it is faulty and it must be replaced.

Possible causes include:
1) Faulty connection due to MEM-CAL not locked in place.
2) Incorrect MEM-CAL installed.
3) Faulty MEM-CAL
