I am having trouble with my truck stalling when I put it into Drive Or reverse. It only happens when it is hot, like if you run to town, go into a store, come back out and go to drive away, then you put it in gear and boom just dies. When it is cold in the mornings it never stalls, but I did notice the other morning that it surges about 50-100 rpm when I first start it. Anyone have any ideas? Is there a away to adjust the idle on these trucks.....mine seems to be around 750 rpm...thought that was a little low.
