Hey fellas...the 351M in the Bronco is really starting to piss me off. For the last week or so, there will be times where it will sputter anywhere from idle to 35mph, sometimes even cut out, but if I feather it, she'll come back alive. Then other times, it sounds like it's running on 5 cylinders. Then days like today, it'll run perfectly. I will say though, when it is running rough, the longer I drive the better it starts to run. I just threw a new fuel filter on there, new plus 500 miles ago, the carb, fuel pump, wires are a year old, new timing chain 2.5 months ago. Any thoughts on where to go next, or which of the new parts could have failed?
