Test your battery, mine would do that when I bought it. Replaced battery, problem solved.

Could be the Idle Air Control valve is sticking. Start the truck, go under the hood, disconnect the IAC valve, and see what the truck does. If it keeps running poorly and basically doesnt change, IAC valve isnt working. If it dies, its probably something else (trucks should still run without the IAC valve, though they will run rough and nearly die).

Any other driveability problems? If so I could see it being the fuel pump. Usually though, if the trucks running poor at idle due to fuel pressure, it will run like garbage or not run at all when you ask for even more fuel. Does it only do this when its cold? Does it get better or worse as it warms up?

Get the code? That would help alot! If you dont have a scanner head over to Oreillys, Advance, or Autozone and theyll scan it and give you the codes for free.

Im almost willing to bet its an IAC valve code especially if it runs well while driving...

I want to say its either the IAC valve or the check valve in the fuel pump. How many miles are on it? Usually the check valve problem will only be for the first start after its sat a little while (unless its really really bad). Get us the codes and well go from there.

I will say this: if the codes they give you do NOT contain an IAC valve code, rent a fuel pressure tester while youre there. Then we can check the fuel pump/check valve...

Fuel pumps often go at or before 150k, though some make it longer. IAC valves vary widely.

It could also be a bad vacuum leak that has suddenly shown up. Do you hear any sucking, hissing, or whistling noises under the hood?

Ask your buddy if his scanner can read long term fuel trims- that might help us too. You may have a "bank 1 too lean" (vacuum leak usually) or "bank 1 too rich" (stuck injector or bad fuel pressure regulator) code instead of an IAC valve code.

I don't hear any whistling or hissing etc under the hood when we plugged up the computer it did say too lean
