Very strange issue I'm having. I'm convinced it is an intermittent vacumn leak due to the inexperienced installation of my header. As long as I let the truck warm up properly after any significant stop, she runs like a champ. I drove all the way home with one stop and no problems. If I don't warm long enough, I get splutter, buck....hesitation. I have conferred with several people and a vacumn leak seems to be the consensus. If tightening up the bolts doesn't help, I will redo the header over the break.
We had a blast in AR. Did some mild offroad stuff in and along a river. pix to follow soon.
Many thanks the Greg for posting my situation up on the AR forum and to Rick the AR Cruiserhead who I conferred with some. It's nice to know there are so many people around the country willing to jump in with assistance when you're on the road. I hope we are as willing to lend a hand when someone breaks down in this area.
