I will try these things and see what happens. I did replace the pedal and it didn’t fix it at all. It’s still doing the same thing.

I will have a better look at it this weekend and check the wiring and inspect the MAF. The throttle body on it is aftermarket, according to the previous owner. It did look new when I took of the cover on the intake.

Sorry I haven’t replied in a while. I appreciate all the input. I have not been able to drive the car as it won’t even make it out of the driveway. I did take the the cat off and it still won’t move. Still wants to bog at idle and when u put it in drive or reverse, it won’t move. I am at a loss. Once it cools down I am able to move it but as soon as I stop, it will move no more. I can only move it when the car is completely cold and only until I come to a stop. So I tried my diag tool again and finally pulled 4 codes. Accel pedal a P0123, accel pedal b P0223, MAF circuit low P0102, and intake air temp circuit high P0113. So now I guess throw parts at it? Lol.

So I don’t know what caused the issue in the first place. The person I got it from said it had a dead accelerator pedal. They tried replacing the throttle body and that didn’t fix it so the person sold it to me. Was hoping to make a nice economic daily out of it. There are no check engine or error codes at all. No pending, history, or current codes. Idk if they cleared them or what but there is nothing.

Hello all, I am new here and also new to Subaru. I just bought a 2010 Legacy 2.5 Auto non turbo. I’m having an issue where there is no acceleration. When in park or neutral, I can press the gas pedal and there is serious hesitation then it slowly clears up and revs up. In drive and reverse, it will not move and doesn’t accelerate. The person I bought it from put a new throttle body on it and it didn’t fix it. There are no check engine codes at all. I read live data, and when I press the gas it shows pedal position accurately. And when I press the pedal in drive, even to 100%, the throttle body shows maybe 60% open. I’m at a loss. Any help would be greatly appreciated.
