Hello, I have a sentra ser spec v 2003 and I have a problem. The auto start but when I press the gas pedal nothing happens I do not have gas. I change the pedal and the throttle. I clear all the error codes but some fades more. I believe that it is an electrical problem. The first error code is P2138. Thank you for helping me

P2138 is for the accelerator pedal position sensor fault, you will need to replace that switch.

SOURCE: Issue with throttle control on my 2003 Maxima

I discovered that its the throttle body sensor. Its not sensing the postion of the foot pedal. The throttle body has a sensor that is linked to your gas pedal via a cable. The spring that the repair man mentioned could be the issue. The sensor then communicates to the computer the position and then computer then applies fuel, the mass air sensor then will communicate to the computer and the computer will then allow more or less air to fuel ratio. So if your stomping on the gas and there is not any response, then your throttle body sensor is most likely going out.

I have a 2003 Nissan Sentra SER SPEC-V and have done all my own work. When the battery was replaced, was the Positive battery terminal taken off first, before the negative terminal? whenever doing work on a car with a ECM, the rule is: Negative terminal is ALWAYS taken off first, then the positive terminal. After changing battery, the positive terminal is put on first and then the negative terminal is put on last. I am not saying that you have an ECM problem but they can be damaged if you take off the positive terminal first.
Do you have any "check Engine Light" code issues? If you do, and you have access to an OBD2 code reader, check if any trouble codes come up. If you do not have access to one, you can go to an Auto Zone or other parts outlet and they will read it for free. Confirm that you have or do not have any Trouble codes. Let me know what you find out.

Can I use 10W30 oil in my 2003 sentra ser spec v?

you can use anything you want
however, 5w30 is advised by Nissan
limitations is that 10w30 will be thicker in the winter and may cause harder starting and/or bearing failure due to lack of oil on start up

but depending on how many miles you already have.... 10w30 should not be a big deal!!!

2003 Nissan Sentra SE-R Spec-V clutch sticking and hard shifting

I am dealing with a very similar issue on my 03 Spec V , So far i noticed the clevis pin was loose and the locking hitch pin that slips thru it had fallen out . this caused the gears to not wanna engage due to the bolt behind the clevis which runs to the master cylinder was not getting pressed in when i pushed the clutch pedal in because the clevis pin was slippin on n off giving me no pressure up top .. I had to remove my lower dash panel in order to get visual n hand access to this pin , it is a tight spot to work in as well . May be easist to remove the 4 14mm bolts that hold yur driver seat in to give ya more room to work n stretch out ur arms
