Hey y'all. Haven't posted here in years. The forum looks completely different. Anyways, my 5.5 gen started doing something weird lately. Has anyone experienced their Maximas stalling out randomly while driving or applying the brakes? I've got a PO300. Coils are old but not original. Dealer is telling me I need to replace them. I will but I don't think it's gonna fix it. I've been battling this code for years. Finally replaced the plenum gasket and I think I fixed it. It has been 22 trips on that code ever since in last reset it. Anyway just seeing if anyone has ever come across this intermittent ghost issue.

 

I had that happen twice in one day last week, but I got the code for the camshaft position sensor (P0340). I replaced that and have had no problem since.

I've also seen it with a knock sensor code, although the code was present long before it started to stall randomly.

 

its camshaft sensors, replace all 3 use OEM or go home,
and yes it will happen and go away, but it will come back and be progressively more
ask me how I know

 

knock sensor code is a piggy back code that literally appears every time any other code comes up

 

If the car stalls at a low rpm 500-800 it might be an issue with the throttle body, you can clean that as well as the MAF sensor with some cleaner, also change air filter if dirty, next it could be a bad EGR valve, you can clean that too plenty of youtube videos or replace the valve

Now if it stalls at a higher rpm 800+ it sounds more like a fuel issue, could be a clogged fuel filter, could be a bad fuel pump, you could test fuel pressure
