miss or stutter 5.3 4X4 (106K)
had a slight miss or stutter between 45 & 55 MPH when at steady speed. Time to change plugs and wires any way so I did it this weekend. Now miss is worse and also happens when accelorating easily in the same speed ranges. Any Ideas??????????

Then if you haven't already I would clean the throttle body real good along with the IAC (which is also in the throttle body) and see how it runs. If it still is not fixed I would start testing the sensors.
