Question about 2003 Nissan Sentra
The car may not recognized its key. I would try another key or see if there is a code for an unauthorized key.

Check for vaccume leaks and also you PCV valve. check the hose too. Visually inspect every vaccume hose you can find. Sounds like a leak .

Hi. The Nissan has been known to have issues with the stock solenoids that are installed by the factory. The transmission also has a OD shift solenoid as well. I would do two things. ONe, check the fluid level if you can. It shouldn't be caped with a plug but, some models have sealed transmissions. If your model has a dip stick, please check the level of the transmission fluid. If the level is ok, i would drop the pan and check the solenoids to make sure that they are working properly. while the pan is dropped, It will be good to visually inspect the bottom of the pan for metal fragments and discolored fluid.If you see anything not normal like black fluid or metal small fragments, this will not be normal. Although, the shift patterns of this model are quite unusual, I would recommend using the instructions above to make sure that this transmission is not malfunctioning.
please rate and have a great weekend..

I had this exact problem a few weeks ago. The repair shop first changed the thermostat. Didn't fix the problem. Next step, they found the radiator was clogged. They replaced the radiator and now everything works fine.
