the 700 rpm failed, that means the ECU has no control of the ISC
on this old car step 1 is not ISC,
step one is this.:
1: insert the diagnostic jumper in the DCL pins (paperclip unbent)
2: the CEL lamp flashes code 12, for happy, other codes even lots more flash out and means failures each.
suzuki,toyota,nissan, what ever 1994 car same answer, only how to get codes varies, see?
if the ECU is in limphome mode (failsafe) idle controls are suspended, see why IDLE CONTROLS ARE LAST.
STEPS,
1: KEY ON CEL GLOWS, IF NOT FIX THIS FIRST.
2: KEY START ENGINE IF LAMP SAYS ON , THERE ARE CODES STORED. GET THEM.
