2011 Elantra code P0011

What is your question?

Hi. I started with a few different codes. I changed the upstream o2 sensor, the crankshaft sensors, both camshaft sensors, the VVT selonoid, and the oil. I now only get the P0011 code and after about 10-15min driving the car stalls then starts when I turn the key but then stalls again unless my foot is on the gas. Any help will be greatly appreciated.

How long has your 2011 Hyundai Elantra had this problem?

More than a week
