I have a 96 Legacy Outback Wagon 5spd 2.2 with recently rebuilt motor (25k ago). I have had problems since day one with it when it comes to acceleration. If I floor the pedal it takes maybe a 1 second to really respond. When I try going off roading up a hill I can't get it to go because of this. I have had 5 subarus and they never had this problem. My 91 legacy climbed way better than this.  I've also been getting 20 to 22 MPG which I usually get more with these cars. No check engine light. I have a donor car so I've been swapping parts. So far I have swapped Front O2 sensor, all 4 injectors, MAF sensor, New PCV valve, New Spark Plugs, pretty sure I did a fuel filter 25k ago, New wires and I've done a fuel system cleaner. What else should I do? Thanks

Try disconnecting the cat (it will be real loud) but then see if acceleration uphill is improved.

If so, the cat may be clogged and the pieces block the flow and even more so on an incline.

I disconnected the cat, replaced TPS and Knock Sensor. Nothing helped.
