I know this isn’t much to go on. I changed the plugs and wires in the fall and all the plugs looked the same, worn out but equal, no oil or carbon fouling.
The check engine light is not on. Is it possible to pull codes even if the check engine light isn’t on? I feel like it is some sensor not working properly and not an internal engine problem. If anyone can suggest a place to start I would appreciate it.

Since I don’t have a check engine light and the knock sensor is basically new I had not considered this to be my problem this time around but the symptoms are about the same other than the weird no shifting. My car drives like the timing is way retarded. Maybe I should look at the knock sensor again.

Knock sensor installation is easy to mess up. Subaru knock sensors are a fickle beast. They have to be installed with a certain orientation and the bolt can not be tightened to more than the factory torque spec or damage can occur to the sensor housing. If moisture gets inside the housing it will cause the piezo-electric component inside to corrode, causing failure of the sensor.
I searched and searched last night for a knock sensor replacement thread and came up empty handed. I have a P0325 code on in the wagon I just bought so I'm going to replace the sensor with a used one I got and I will make a picture write-up detailing some of the specifics of knock sensor replacement on the EJ series engines. I should have it posted sometime this evening.

SOmeone said snap-on has a 12mm magnetic socket. Sounds like the perfect tool. ALways a little frustrating to get that bold in there.
Remove airbox, pay attention to the orientation of the wire. Install bolt before plugging into harness.
