Hi Tinkerbelle,
I'm in Dogtown in StL now. Watch your step. Overrated.

OBD socket 2 code 2-3-2 is:
2-3-2*
Fuel trim (lambda control) too lean or too rich at idle
At idle means (we hope) not a serious air intake or exhaust imbalance as measured by the AMM on intake and 02 sensor on in the exhaust.
Did you check socket six (ignition engine control)?
Your 1992 Volvo 740 (non turbo) is Bendix Rex ignition / Regina fuel injection with the square ignition coil?
Please advice,
