30,000 miles is when your owners manual tells ya to change plugs. You should spring for new plug wires at the same time. Champion double platinum plugs gapped at .045" will cure the off idle stumble. Magnecore wires are the best (My personal choice). If a coil change is also decided on, the Screamin Demon coil is a good choice. Check out the thread about spark plug gaps, I have lots of pictures taken when I changed my plugs and wires on my 2003 non turbo automatic PT.
