Re: 96 Ram 1500 318 stalling
TPS could be the problem, however, I think it sounds more like the IAC is sticking. IAC = Idle Air Control, it's located on the back of the throttle body, it's a little plunger thing that controls the amount of air that is let into the engine at idle. when you are driving, the IAC is closed(air is coming in through the throttle blades) when you let off of the gas, the throttle blades close compleatly and the IAC takes over. if it is sticking, it can't open fast eanough and the engine will stall. if you remove the air hat, you should be able to access the IAC. you can pull the IAC off and clean it with some carb cleaner, and that should take care of the problem. just make sure that you do NOT move the plunger part when you have the IAC off, as this may damage the internal parts. also, there is an O-ring that seals the IAC housing to the throttle body, make sure not to loose or damage it.
hope this helps some,
Keith
