I have remove cat few months ago (decat), and control lamp in dash bord went on. Today i disconnected 2nd lamda sensor (as some of you did) and control lamp is still on.
I just disconnected the sensor under the car(and i didnt remove sensor), i started the car, and the control lamp is still there! What am i doing wrong?
Car is Clio 1.4 16v (2002).
