Hi. To reset the learing of the ecu concerning the O2 sensors and AFM etc is it three ignitions on and three ignitions off.

This is exactly what works on newer Nissans. what do you know????? these are old cars.My Nissan knowledge only goes back so far. and its toooooooo late in the evening to go try these things... hehe.

Disconnect the battery for an hour or so, overnight if you get the chance, this should reset the ecu.
