I have a 6 cylinder 2001 Highlander. Have been experiencing "stalling" problems, seems like air / fuel mixture goes out of wack. Engine almost dies, then takes off again (very dangerous in traffic). Check engine light use to come on and go off...........finally came on and stayed on. Codes read 1130 and 1150. Anyone know what this means and what I have to do and/or replace to fix the problem?

Would appreciate any help.

Those codes both relate to your front air fuel ratio sensors, banks 1 and 2.
