1990 F250 Idling Problem

Here is the exact situation, when i first start my truck sometimes it stalls right away or it waits for me to go into reverse or drive before it stalls out, then it idles rough for a bit but after its been going for a few its ok any ideas?

I also have a thing where when i first drive from time to time my brakes lock up in the rear completely when i just gently touch the brakes any advice on either would be great thanks.

-It is a 4.9L V6 Straight 6. 3 Speed RWD

Ford Fuel Injection » How To Run a Self-Test Here is a link on how to get any trouble codes. An easier way is to buy an Equus 3145 code reader for around $30.00. Worth checking for codes even if no light is on.
As for the brakes it may be that the shoes need adjusted or it may be the type of shoe lining. However it would be worth pulling the drums to check that the linings are not contaminated with fluid/badly worn and that all the hardware is good.

I had a leaking rear axle tube seal that allowed a slight amount of gear oil to get on my brake shoes. There was no oil leaking externally. That little amount of gear oil caused my rear to lock up. I remember one side (leaky side) locking up while the other brakes would barely would slow me down from light application of pedal.
