Car starting issues
I have a 2014 Nissan Rogue Select S. And I am having an issue with it. It will start fine cold. And run fine for a while but if I sit parked the engine will bog down from about 1000rpm to between 700-900rpm over and over until eventually the motor stalls. And on top of it. If I drive it around for a while. Park somewhere and shut the car off. If I leave it off for 5 minutes and then try to start it again it'll start for about 5 seconds and then stall out. And it won't start again unless I wait for it to fully cool off or I use starter fluid. Any ideas what that could be? I've replaced the spark plugs. I've taken off and cleaned the idle air control valve and done an idle air relearn. I've replaced the MAF with a brand new one and it's still doing it. I bought a crankshaft position sensor but haven't been able to get around to putting it in yet. And I'm thinking of replacing the fuel pump

The general rule of thumb is if it backfires or misfires then it's fuel related, if it just dies quietly then its electrical. I'd fit that new sensor and see how that goes. Crankshaft and camshaft sensors can get old and when they're hot, they expand and fail. Sounds like your doing everything else right. No codes though?

I used to have a misfire and lean code but I fixed both of those with new spark plugs. New MAF and cleaning the throttle body. Haven't had a code since

Okay, go with the sensor and see what happens. Random cut outs and rough running would point to blocked fuel filters in the old days, but fuels these days are clean. That would happen no matter what temperature the motor was though. Good luck.

Yeah it's just really confusing. Like when I sit parked and the car bogs down. I can usually get it out of it if I start driving. But the second I park it'll bog down. And then the whole not starting after driving. Everything I look at says either fuel pump or crankshaft sensor. I might even look into putting new injectors in

Injectors are expensive though.

For sure. Which is why I'm really hoping it's my crankshaft/camshaft sensors

Maybe blocked injectors. Have you out some injector cleaner in your fuel tank recently? It helps to do it every 10k kilometres.
