All stock. Car engine made a subtle noise when i got to my destination and parked. Left the car on looking for the noise. It didn't sound like a knock. Sounded like a rattle from my exhaust but wasn't. Revved it a little but sounded normal. Turned it off and back on and it was rough. It wanted to shut off. So I turned it off, came back an hour later, started and drove off. A few blocks down engine was sputtering, gave it gas and it didn't go. No engine response. It died eventually. Parked it and had it towed. Engine service soon. No other light on. No other engine problems besides an oil leak which I think is from the oil cooler and tps sensor I cleared and didn't come back. What could be it?

 

Is there any oil in it?

Is there any gas in it?

What was the code #

 

Definitely need more info

 

No oil!

How often do you check your oil and when was the last time you checked it?

Is there gas in the tank?

Your throttle body might have taken a crap on you. Here's more information on the P0506: https://www.engine-codes.com/p0506_infiniti.html

 

Do the idle air relearn and ecu reset procedure and see if the problem fixes itself.

I'll give it a go but the battery dead all of a sudden. Weird, and I "cleared" the code but engine service still on.

 

Have the battery tested and replace if needed since it sounds like you just found the smoking gun. A bad battery causes all manner of wierd issues on a vehicle that is basically a giant computer.

 

Got a new battery put in and gave it a go but it didn't want to turn over. And im confused, the engine service light is still on. My buddy cleared it with his scanner and with a new battery put in should reset the ecu. I'll update tomorrow. It got cold and foggy. Thanks you guys for the help.

 

Battery has to be out for about an hour to drain off enough residual voltage to reset the ECU, less time if you pump the brakes. You're sure the security light isn't solid red?

 

One of the advantages of having the dealer replace your battery is that the vehicle will be running when you pick it up.

what security light? I disconnected the negative and pumped multiple times and it's not reset. Do i have to floor it hard or what?

edit: meant to say car won't start

 

 

The security light is on the dash to the left of the instrument cluster, an LED embedded in the dash to let you know the status of NATS. A solid red light means NATS has interlocked the ability to start the vehicle.

Did you unplug the throttle bodies at any time during your troubleshooting?
