Dude, I threw so many parts at it that time I honestly can't tell you what actually fixed it. It's like a combination of things went bad all at once. Sent from my iPhone4 using Tapatalk

Well I had a little trouble over the past few days with my coil pack install. After completeing everything the stumble that I was trying to cure actually became worse and after about 25 miles I threw a cylinder 4 misfire code, so I started the whole process over. I thought that it may have been because my new plug gap was too large, .065", so I bought new Autolite Platinums and gapped them to .054". I took out the cylinder 4 plug and it had a hairline crack on each side of the porcelain. But I figured I'd replace all the plugs while I was at it. After finishing that I replaced both my EGR Valve and DPFE Sensor and now my truck runs like it should. Excellent throttle response with ZERO stumble. Much thanks to Darth Bama for the help!
