I just got a 78 bronco. It has the 351m with 2150 carb. I have rebuilt the carb and still have the same problem. After it warms up and while in park the rpm's are around 2000 Maybe a little more. When I shift it into drive it idles down to the point it almost dyes. I can't figure it out. I have noticed a few things have been plugged on the carb. One in the front bottom and two in the back. The coffee can looking thing is not even hooked up either.
