This is the problem: when I try to accelerate from a dead stop to an acceleration point on an uphill my truck seems to have a flat spot. So, i need to know what I should be looking for that could be causing the problem. Now when I'm on the highway and I'm accelerating up a hill I just turn off the over drive and that gives me the extra acceleration to keep my regular speed that I'm going on the highway. So, if somebody has any ideas of a starting point,let me know. My wife says get rid of it, My reply is buy me a brand new truck and I will and that usually shuts her down. I have no plans of getting rid of my bronco, I like it too much. So, any help would be appreciated.
