I have discoveredmy air intake hose hase a small tear and also has a melted area near the edge of throttle body. (It melted probably last yr when i had over -heating issues I assume.)

HELP. I have replaced the 02 SENSOR as well. I am told my COOLANT SENSOR is bad too. DOES any of this cause that extreme gass usage??
