Starts but will not stay running

Just so I am clear, your engine was running fine and all you did was change the plugs and now it starts but cuts off?

What engine do you have? I attached the procedures for the 3.6L and 5.7L. Give them a look and see if you missed something.

I would double check the work. Make sure the plug wires are back on the correct plugs. Let me know if anything jumps out that we may have missed and we can go from there. Thanks
