| try disconnecting the edge chip and see what happens. Did you run your tank low on fuel recently? I think there is a TSB for #3 and #7 injector harness plugs too. Do you have access to a code reader? It would be good to know what codes you have too. Wow, only 9500 miles on an 05....does it sit for long periods without driving? Just wanted to know if your fuel filter change was only 500 miles or 5000 miles ago.
