any ideas?

so i found and changed out the downstream sensor but i am still getting the same error (s) 0125 1133 1135 i replaced the thermostat the coolant is filled and the ect sensor is changed (the one by the coolant return on top of the engine) now i am wondering, there was a sensor on the thermostat housing. could that sensor be the one i need changing?

thanks to all of you... :D

hi all... i keep getting an error code 0125 so far i replaced the thermostat the ect sensor and filled back with antifreeze error keeps poping up next step is the o2 sensor as it could be that or a leaking exhaust (tried that for a little bit but it doesn't seem to leak) i can't find bank 1,2 sensor 1 actually after searching i find only two sensors one on bank one by the firewall and one on bank two by the radiator. any tips... hints?
