I have a 2001 Nissan Sentra automatic transmission with 172,000 miles And with a BlueDriver scan tool I got the code P1320. Now what happens is after I take at least a 40 minute drive or longer towards the end of my drives I will press on the break and the car just shuts off so then I have to shut it off put it in park and restart it again, and then will continue to do that and sometimes when it’s just idling after a long drive. Please help
The engine code page is here: https://www.engine-codes.com/p1320_nissan.html
As the page indicates, the most common of the causes discussed is an faulty ignition coil. Have those checked first.
In other words, don't go to a "I change parts before I diagnosis" mechanic. You don't want to pay for parts swaps that don't fix the problem. You want someone who will test and diagnose, before any work will be done.
If they won't guarantee the fix, walk away.
Is there a video link you could send me showing how to test my ignition coils?
