2004 CTS V throwing a P1125 code and having intermittent "engine power reduced" message, followed by a slightly rougher idle and definite lack of power. The throttle pedal position sensor (APP) has been discontinued by all manufacturers, OE and aftermarket.
I figured there's gotta be something I can do to get around this being how big LS swaps are.

Has anyone seen anything like this before? What can I do here to get this car running normally again? My last resort will be taking it to a corvette specialist shop but trying to keep it on the budget side for now.

Thanks in advance.

I found this on Rock Auto. Idk how long you'd be without your V though.
