95 Dodge Ram 1500 318 idling problem

My best friend has a 95 Dodge Ram 1500 with the 318 V8 and when he starts it in the morning and backs out onto the street it dies when he puts it in drive. That is the ONLY time it ever dies on him. It is fine the rest of the day. We live in Missouri and it has been cold here. Any ideas what could cause this? I cleaned the Throttle plate and the thing just runs perrrrfect otherwise. No check light or anything.
Thanks,
Rob

No one has an idea for me on this? I still can't figure out why it does this.
Rob

did you try cleaning the IAC valve? its on the back of the throttle body, held in with two torx screws.

I have not had time to get ahold of that truck to clean the IAC but will soon. Maybe on Sat. He said it has not been dying since the weather has warmed up a bit.
Thanks!

We cleaned the IAC but the truck still stalls sometimes. Any other ideas on this?

Dirty injectors. Dirty throttle body. Tune it up, clean everything...

you may want to have a shop ckeck the coolant temp sensor on a cold morning before its started for the first time. sometimes these can develope a bad spot at a certai temp range.

Try getting a new throttle positioning sensor. Kind of expensive but you can pick it up and install it yourself at Auto Zone. It's located on the top, driver's side of the engine.

LTJGWorth, the TPS is not the solution for everything.

Clean the throttle body. Take it off of the intake get a can of carb or t/body cleaner, I can almost bet that there is a build up below the butterflies. also while you have it off pull the iac motor off and clean it too.

I've got the same truck. Did it once to. I connected a fual gauge and found out wasn't getting appropriate psi. Also ran great for the rest of the day. But mpg got worse slowley and didn't realize til you think back. So bought a fuel pump from Chysler. NOT FROM AUTOZONE OR WHATEVER AUTO STORE. These don't work the same and if do will got out soon. Reson having lifetime warranty. Also went with a tune up. Autolite best plugs I've ever done in my LIFE. Well worth it.

Yes it is!!! It is the answer to all that needs answering! But seriously, i'm just going with past experience. Anything helps right? BTW I love the TPS!

Indyram, the TPS might actually be the solution to this problem. It's not the solution to all of them, but it just might be the answer to this one...
