I hear ya MoparsnMissiles. It was all too weird for me to figure out but the dealer eventually did. It was 4 years and 167,000 miles ago that this happened, but I'm almost positive it was the ABS you mentioned and it most definitely made it run like crap. Since the repair it has never done it again, and I have over 267,000 miles on it now. Untouched motor and trans. Best truck I have ever owned bar none!
