My D idles smooth as silk on cold start, but after 5-10min. of warm-up it starts to surge up and down at idle. It does this all the time and have yet to find the problem. The car also hestitaes on accel but "kicks" in at about 2500 rpm(Kinda like a turbo kicks in, no I don't have a turbo! LOL), any suggestions???
