Guys i have the same problem but sometimes lambda starting to work properly for a 1 minute or 2... and no error code from ECU. do i need to change it ?
where is lambda ? i was thinking that it is on catalic converter... what is the sensor on catalic converter ?
okay then, for the time that i'll wait the plate (i need to order it :( ) i can use my greddy gauge as water temp.. can i install this sensor somewhere radiator or smth ???
