PCM memory error code

Odds are one of the capacitors failed, or is out of range (failing, but maybe not quite dead). I've repaired a couple. Chrysler uses 220 and 470 uF electrolytic caps that offer just enough energy for the PCM to update the EEPROM on shut-down (or in your case -- not). If you pull it apart, the caps are the round things. Read the part number, look it up, desolder the old ones (just shoot for replacing them all), and solder the new replacement on. Digikey.com and Mouser.com are 2 good places to get replacements.
