[QUOTE="Toxicity JK, post: 460381, member: 25416"] Still no solution. Coil pack was replaced last week. developed a misfire on cylinder 1 so I thought it was the culmination of the hesitation issue. Replaced the coil pack and it fixed the constant cylinder 1 misfire but the hesitation issue continued. I'm down to fuel pump, EGR valve, or wiring issue somewhere. All are relatively inexpensive parts but pains to replace. [/QUOTE]
