engine shuting off
i live up in morgantown wv and the temperature in the winter is always cold. on cold days when i got out to start the truck, it starts and then the battery strength indicator goes way down and the truck shuts off. to keep the car on, after i start it, i can keep my foot on the gas and as long as i keep the rpms up, the truck will stay on and the battery indicator says at a normal level. if i do this until the truck gets warm then it runs fine. if i let the rpms get too low, it shuts off, even if the truck is in drive.
i have gone through the haynes manuel and cannot seem to find what the problem could even be. also, when the truck is parked in northern virginia where the temp does not get as low, the truck starts fine, no problems.
1996 Bronco Eddie Bauer 5.8 with tow package, no code pulled yet, but the light has been going on and off. will do on monday or as soon after as i can.
thanks

Sounds like it could be your alternator, or maybe worst case secenario could be your torque converter. Torque converter could be locking up, with fluid being cold and thicker, then when it warms up the fluid thins down and circulates easier. Had this problem before and it was the torque converter.

Codes first. If that yields nothing definitive, have the electrical system tested one component at a time starting with the battery itself. Does the charge indicator light on the dashboard come on? Does it ever go off?

i am going to get the codes pulled later today. but the battery light operates normals and only lights up when the truck is started and when it is about to die. if i stay on the gas or the truck starts normally, the battery light never comes on. ill post back as soon as i get the codes pulled.

This is a chicken or the egg question, is the voltage dropping because the engine is not maintaining idle rpm, or is the engine shutting off due to low electrical power. Welp here is my quick check, on a cold day, I would throw a battery charger on it, one of those nice ones that have enough current to engine start, or if you dont have one, use another vehicle with a set of booster cables. This will supply enough electrical power to run the vehicle to eliminate a charging problem so you dont end up on a wild goose chase.

wasnt able to get to the shop to check the codes today, but i did check the volatage on the battery, tested the acid, and since the battery had 14 volts on it when the truck was on i believe that this is the check to see if the alternator is working. so i believe that the battery, and alternator are in fine shape. so i codes will have to tell

No bad codes... it only does it when it is really cold... hmmmm... first thing I would do is find all your ground cables that attach from your engine to the frame and drill holes through them and put in some screws to make sure you have a good ground at all times. I am guessing but I think the cold weather is causing you to lose ground so your alternator loses voltage and your engine stalls.

I am going to go out on a limb and say it is not electrical. Does your truck have a cold idle?? Does the engine RPM's idle at 1000 RPM's or above when you first start your truck?? When the truck is warmed up it runs fine ya said. If I were you I would look some where else than the electrical. It is isolated only to very cold starts and no other episodes. From my experience, and ground problem would screw you up on warm days, cold days, and good days! Just my thoughts.

Just crawl under the truck and you will see braided ground straps In the front passenger side of the engine and the rear of the engine on the passenger side. They are easy to spot. You will see one of fords good ideals... these straps are just clamped on to the frame and the engine. They do not work that well. I am just guessing but it wouldn't hurt to giggle them and see if you can't get a better ground.
