I drove through some flood water that was maybe 1-2 foot deep and my truck began running badly, lost power and spits and sputters. It's run horrible ever since. It shows codes p0031 and p0037 any suggestions?

Hello,

It is possible to get water into the electrical components or even into the engine, depending on how high the water got as you were driving through.
That can impact the way the vehicle drives or can prevent it from starting or driving.

What have you done, in terms of inspecting under the hood and components?

Have you checked to see if there is water in the air filter box? What about water in oil?

Any electrical issues?

Both of those codes are Oxygen sensor codes. It's likely due to getting the harness wet.

Please let me know a little more of what you have been experiencing.
Thank you.
