Hey everyone, a relative of mine has an 03 Tahoe that I'm trying to get back on the road that's been having a bit of a mystery issue. It runs and drive seemingly without issue but then it suddenly shuts off. I was on a test drive and everything seemed to be going well until I went over a bump and it stuttered. Wanting to recreate the issue, I turned and braked while going over a bit of a bump and sure enough it shut down completely. The codes showing up are P0120, P0220, P1516, and P2135. I personally think there's clearly something between the pedal and throttle body that's just not working right, whether that be a connector, wiring, or even the sensors themselves. If anyone has had an issue like this before it would be great if you had any input on what fixed your vehicle or any helpful troubleshooting tips, thanks.
