Default 2003 Sentra Code 1121

My check engine light recently came on. I took it to autozone and they told me the code was P1121, and they gave me some stuff to put into the gas to clean everything off. Then when trying to leave, my car started but when I pressed the gas pedal it would not rev up. I started the car 2 times after that and finally it started up again.

I was able to put the stuff in the tank and I drove it for the next two days(the check engine light remained on). Then it repeated the earlier problem where it would start but not rev up, only this time turning the car off and restarting several times did not work. Any ideas?

Until a Specialist responds...I found this in your Service Manual SECTION EC - ENGINE CONTROL SYSTEM.

Here are just a few pages relating to your 1121...

The code is for the electronic throttle body. You may need a new one. Nissan offers remanufactured units.
