Try disconnecting the Oxygen sensor. It might be bad and sending a false lean signal. The car should run OK without it, for testing purposes.

Or it might be a bad ECT (Engine Coolant Temp) sensor telling the ECU that it's —35° outside. Testing procedure is in the 700/900 FAQ (same engine as 240).

The ECT is not easy to access for checking or replacing. An Ohmeter test is easier done from the ECU connecter.
