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?
