Hey all, just found this forum and thought I'd put something out there. I've got a 2018 Titan Pro4-x with about 70,000 kms(43,500miles) I am having an intermittent startup issue, when it starts it almost sounds like it's running out of time, very rough idle won't take throttle well and shakes like crazy. I had this happen a couple of years ago, fou d I had a weak battery, changed the battery and upgraded to an AGM battery and the problem disappeared till about two months ago and it has happened about three times now. I would say it happens more after engine is warm and sits for anywhere from 10 minutes to an hour historically. I have scanned the ecu and have only one history code that may be related P0725- engine rotation. There has never been a MIL or any active codes set when scanned. I haven't looked any deeper into P0725 other than know that it is there as annjnactive code. Anyone else experienced this?
 
Honestly sounds like a crank sensor or wiring issue especially with that P0725 lingering in the background.
