hey guys i hope you can give me some insight into this problem ive been having whenever i start my truck i let idle for a couple of minutes then put it in gear and it just stalls right out which i then can usually start it right up again usually the first try. Today i just had the computer reflashed and still doin it by the way i have a 2005 ram 1500 with the hemi any help will be useful thanks in advance. By the way im in Buffalo and it is cold but its done it to me when it was decent out to .

 

Might be a dirty throttlebody. This can cause the blade to stick and not open up fast enough to keep the idle up when you drop it in gear.
