Hey there all! I'm really hoping someone can help me out with this as I'm going nuts.

I recently had some misfires and the car was running rough, so I did some maintenance. I ended up having a leaking valve cover gasket, so I got that swapped out. Turns out I also had a bad fuel injector (read 2k ohms), and I got that swapped out too! Now the car is running fantastic. Stable idle (finally), feels snappy and responsive again.

But after the valve cover gasket replacement, I started getting an A731 error. I can't figure out what could be causing this, and besides that error code I can't find anything electrical that isn't operating as it should.

I would love some advice! Thanks in advance!
