06 H3 Hummer not keeping an idle on 2006 Hummer H3

Ok new here and need help. I have an 06 H3 that has a difficult time keeping an idle. It starts up ok but i have to keep giving it gas so it does'nt die. When driving and i slow down to turn a corner it dies and i have to drop it in nutral to start it. I have replace the battery and has not helped. Thinking about replacing the spark plugs and if that does'nt help i'll replace the alternator. Just not sure if these items are the cause. Can anyone help me with this or give me any advise on what could be causing this issue. Thanks

Stop replacing parts not needed! Take it to your local mechanic. It may be something simple as a vacuum leak or a idle air motor?
