hey guys,I started my 91 SC today and ran codes,as you might recall,I have been having trouble with it not starting right after you shut it off,anyhow,heres what i got :
Engine Control System operating in Fauilure mode and Effects Management (FMEM) programming strategy..Can anyone translate that into plain english for me?:confused:
 
Code 98 puts the Engine Control Assembly computer into what some call the "limp home" mode. Default sensor values are used for the EEC system to attempt to keep the vehicle operating until it can be taken to a mechanic. This mode occurs when a major component or computer failure has occurred and the computer needs values to operate the vehicle well enough to drive. I would see if something is unplugged or maybe the wiring harness to something has been damaged. Otherwise something major, even the EEC itself, has failed.
