I NEED TO FIND OUT WHY MY CAR WILL NOT RUN WITHOUT MY FOOT ON THE GAS, THE ENGINE WAS JUST REBUILT.

I have a 03' Altima 2.5L that had the engine rebuilt. It had a timing problem from initial start up and bent valves on the original head. The head was replaced and timing reset, only to find out that the timing chain tensioner was bad. Changed the tensioner, and it started. Now the issue is the engine will not stay running without your foot on the gas. As soon as you let the pedal out to let it idle, it stalls. At about 1500 rpm, it sounds as if it is pinging. The trouble codes it threw out were p1122, p0223, p0123, p2135, p0300, p1122, p0223, p0123, and p2135. What could be the cause of this?
All these codes have to do with the TPS. Check your connections to the throttle, make sure there are no bent pins. If you need diagrams I can supply a few.
Just real quick, it is a cable throttle with a TPS sensor? Or is it a electronic throttle body?
I looked at the pins and connector, there are no bent pins, nor dirt, grease, oil, or crap in the plug.
With so many codes on the same component, the most likely cause would be a bad connection. If the TP sensor was removed, it could have been installed out of position.

It was never removed from the throttle body. The throttle body was never removed from the plenum.
When u did the job, u didnt remove the engine did you? Or did u just pull the head?
