some PGM-FI problems will also make the @ indicator light come on. After repairing the pGM-Fr system, disconnectthe BACK UP tuse (7.5 Al in the under-hood fuse/relay box tor more than 1o seconds to reset the TcM memorv.
NOTE:
a PGM-FI svstem
The PGM-FI system on this model is a sequential multipon fuel iniection svstem.' Disconnecting the BACK UP tuse also cancels the radio anti-theft code, preset stations and the clock setting.
