Hummer H2 Sensor Problem

Trouble code P0101 comes on. Replaced the MAF sensor, 02 sensor and it still wont run properly. Wont drive at all engine acts like it wants to die when put in gear sounds almost like it's missfiring. Cleared code several times but still barely runs. Only code that comes up is P0101 total loss where to look!
HELP cant even drive to shop.
