Why do I get traction control light on with evap leak, mass air flow, and two 02

The mass air flow keeps blowing a fuse.. so changed the sensor and the fuse. And it blew again. The traction control light comes on and the car starts jerking and pulling..

Anytime there is a malfunction within any of the *engine operating systems* - traction control is rendered inoperative by default .. Then the Trac Off light turns on!
