Maybe the intake leak is causing it to go rich by teling the computer its running lean by sucking air.I had the famous intake leak and didnt even know it till i changed it,i was throwing a code but i dont remember wich 1 it was.I wanna say 131.just change it if you think its leaking cause its a famous issue with these things. its easy you can do it by not even taking the complete intake off the motor,just throw a 2x4 under it pull the gaskets and replace .
