1. Most or all Subarus got r134a refrigerant in MY '94

 

2. Either as an option or standard, most Impreza models could have a 2.2l engine in MYs '95 - '01

 

3. Subarus got OBD2 in MY '95

1: I believe all except '94 Loyale and Justy.

2: Option in '95, standard except MT Brighton in '96-'97, no 1.8l for '98.

3: 2.2l+AT is the drivetrain configuration that had OBDII in '95.

My 95 Legacy L wagon with 5-speed MT also has OBDII. I can't see why they'd only put it in AT models when the ECU controls the engine, not the tranny.

It might be different with Canadian vehicles, especially if they (or your particular car) were manufactured later in the production run. I know some '95 Imprezas actually corresponded to '96 lineup. At the very least, one can say that among '95 North American 2.2 MT models, there certainly were those w/o OBDII. Also, there were some differences in engine control systems between AT and MT. For example, AT models had EGR system and manifold pressure sensor. And ECU does communicate with TCU. One can imagine that in general, an accurate emission control, which is the purpose of OBDII, is easier to implement with AT and perhaps that's why the system was phased in beginning with those models.
