Default 2003 Idle skip and low power

I have a 2003 four wheel drive dakota with the 3.9 and a automatic transmission . Here lately is has loss power and has a low idle miss. The check engine light came on and I checked the codes and I had po442 and po455. I found two vacuum lines that were bad, I fixed them and still have the idle miss not bad but still there. I also notice that when you tap the gas pedal that it sounds like it is sucking air at the throttle body. Is this normal or not? Could cleaning the throttle body help this. I also have put new plugs, wires, cap, and rotor button on it. Any help would be welcome!

Try cleaning the throttle body and clearing the code. If it reappears then look for another possibly vacuum leak.
