Hmm I’m kind of out of ideas for remote help. Any chance the AC compressor is going out and just poor timing after the cooling service (I highly doubt it)? I’ve never seen one put extra load on the system to make it overheat but I’m kind of lost here. Running lean would run hotter but your fuel trims don’t indicate that and you don’t have any fuel trim faults, all your ***** new and both banks seem to be balanced. Your in SoCal there should be some good shops down there but remotely (and not a Nissan specialist) I’m drawing a blank.
