Old fart memory thing going on here... should be left (drivers side under
the instrument panel) pretty much against the kick pad. The PCM would
protrude into the engine compartment with the 60 pin connector attached by a
bolt with a 10mm head. Look down between the booster and the fender along
the firewall for the harness and connector...
Now... I have some foggy recollection that the PCM on the 85/86 MY *may*
have been located in the centre of the instrument panel somewhere around the
radio... My oldest manual is for a 92, so that's no help.... And I rarely
get to work on older units.
FWIW, it is rare for a PCM to go bad.
Thanks for the come back.I will check that area.Also I have been told that
they dont normally go bad, but its the next thing to check according to
the mech.It will idle very high or not at all.Then runs very rich. THanks
