Every now and then when I slow down at a stop light, the engine stalls. I can no longer trust that this truck can get me from point a to point b without stalling. Any ideas would be appreciated. If it's a short or loose ground, where would I begin to look?

my transfer case was not going into gears right with my 4x4 gm sierra 2500 1999 model. i refilled it with the transfer oil. but i am hearing a whistle noise, it is shifting now and not jumping like the emergency brake is on..do you know what the whistle noise could be???? I am stuck in the mountains needing to go back to ms. should i trust it???

how can you check to see if the transfer case for my 4x4 needs fluid

I replaced all the brake lines with Cunifer then bled them at the wheels. The one that goes from the control box (under cab) to rear wheels is leaking. It is screwed in fully and tight but when pressure is applied fluid comes out around the line/fitting. I flared them all the same but none of the others leak. I tried to cut and re-flare it, same problem. Does this one use a different flare? Could it be a problem with the control box? Not sure what to do. Help!

replaced fuel pump and fuel filter truck still no start, thanks for any advise !

I have 1990 GMC sierra 2500. i need to find out if it has abs brakes for axle replacement.
