After further research, checking for bad grounds, ac compressor, wires, coil pack, I found that a sticking egr valve seems to have been the problem. Sticking open after driving for a bit. I am gonna put more miles on to confirm but I cleaned it and seems to be fine now. Thanks for all the help and if it comes back I will ask more questions. Thanks again everyone.

Ok I see it. It says EJ22. Tomorrow I am gonna check out some wiring, grounds ect. Anyone think a possible o2 sensor issue? With loss of power/bogging down. Just a thought. But really only issue with ac/defrost

I drive it daily to and from work. The only time I have an issue is with AC or defrost. And if I remember correctly th defrost uses the ac compressor

external cables look good but I will definitely explore internal grounds and cables. issue is surely happening under load

after 20 mins of running I got in the car turned on the lights the radio and stepped on the brakes, it bogged down pretty good but never shut off, never got a check engine light. I am gonna look for a used coil pack and try that. also how would I check valve clearance?

so I did the altenator test and when I had the defrost then AC max on it stayed running. did bog down with no check engine light yet, but still running after 10 mins

Not sure how to tell engine type I will include pic. It has 170k miles. I did replace the battery last week. Tried disconnecting the battery but not with a load. I will test that next

Hi, I am new to subarus and forums. but thought I would give it a shot. I bought a 96 legacy LS a month ago. one morning I had to turn on defrost and after a few minutes the check engine light came on and the car started running a little rough. when I turned the defrost off car cleared up. check engine light went off a day or 2 later. same thing happened with the AC on, so I took it and had the code read. misfire 3 was what I got. so I changed plugs and wires. next morning same thing with defrost and same reading. what would be next? Thanks!
