Default subaru baja misfiring and backfiring under accelertation

2003 Subaru baja 100k miles on it.
The car will run perfect under hard acceleration untill I drive it for about 5 minutes, then when i give it more than Half throttle it will start to stutter, backfire and miss on Cylinder 3, I have tested the spark plug wires, looked at the spark plugs, installed new fuel filter, and put in a new throttle body with the 3 sensors, As to no avail. I was also thinking maybe it has a bad fuel injector, but that wouldnt explain why it runs perfect when its cold. Has anyone had these same problems? thanks.
