On low speeds, such as on my driveway, if going up it feels like it shudders and the gets a better but I feel something right at higher speeds but still drives okay. Battery was drained, out a new one, only code I see is this.
Also had these engine codes before I replaced the battery, changed the battery and deleted them and they went away, but check engine light was never on and is not on now.

The p1724 code and the is the one P0021 code is giving us a clue it could be the camshaft sensor or a problem in the VVT system. Here is what is said.

P1724: Subaru does not utilize this specific code.

P0021: This code is defined as "Camshaft Position 'A' - Timing Over-Advanced or System Performance (Bank 2)."

Here is the camshaft sensor location. Check out the images (below). Let us know what happens and please upload pictures or videos of the problem so we can see what's going on.

Can you tell me what oil viscosity goes in these? It was actually over filled and I don't know what was used before.
