07 G35 idle problem, ecm reset procedure help please



I just replaced the positive terminal fusable link and now my idle is stammering even dies when put in drive. I have a keyless push start fob so most procedures on internet are useless to me as i don't have ability to go from start to on without vehicle being completely turned off between. Its worth noting that it burnt 2 alternators before but ran fine after besides the transmission having some issues down shifting. Does anyone know the reset or reprogram procedures for 2007 infiniti G 35 ECM. Any help would be greatly appreciated. Have a 18 month old and can't risk a break down with him in car while Corona threat from anybody kind enough to stop for help. Thanks for your time
