Bringing up the fsm actually kind of confirms it for me. Since it was mentioned in the 96 obd2 manual I think it only changed in the obd2 cars. Nissan would have been extra proud to put extra functions in the manual as soon as it was available. My timing is bang on 15 at idle (via light and datascan) the switch is reading as off so I'm assuming that's it died in neutral position. Doesn't change anything putting it in gear. I've been reading around and most people seem to say the factory manual cars dont have the timing affected by the neutral switch. Obd1 cars
