That's limp-home mode. Why it's doing that, can't tell.

Not sure where you can check for pending codes, but there won't be an oil pressure reading as our cars have an oil pressure switch, not sensor, so the ECU doesn't get pressure readings, just 0 or 1 from the switch.

No pending codes, no new codes, the check engine light never even came on.

Is there a way to check the oil pressure??? and the car has been fine since... hopefully it was a fluke..

I know the dealer can do it, otherwise you have to T the switch with a port for hooking up a pressure sensor. There was a thread around here or 370z about doing it.

I wonder how much they would charge?? I seen that wright up. I did not want to go that route till the warranty is over. But I guess I could do it, get a reading then put it back to stock..
