hello. ive been working on my 12 maxima for couple months. it lost power while driving n idlesometimes. ive changed out the alternator three times , changed maf sensors, fuse block connectors, fuses, rewired the alternator plug, new battery. i still cant stp it from losing power or get rid of the code. i even got a new ecu and it still operated the same. please anyone hve any ideas.?

 

Disconnect the battery, and if possible, leave it disconnected a few days. Dont forget to ground the positive cable thru a low resistive load to make sure the pcm loses its mind. You may have a wiring issue (green crusties, broken wire, bad ground) so prepare to spend some quality time with a wiring diagram.
