The Trucks starts fine and drives anywhere but afterI turn of engine then after a few minutes try to start it again it turns over and but does not start I can however get it started by putting my foot slightly on the gas pedal and then while engine is slightl speeded up by foot baely giving it gas I can put truck into Drive and then it runs and does not stall I am hoping I can just turn up the idle and see if that fixes it but I do not know how to adjust the idle . The idle is really low

 

Try cleaning the throttle plate on your throttle body. If gooky stuff (<-------fancy technical term) from the EGR valve has built up, it will starve the engine for air and it will want to stall or not start. It's simple (like me) and cheap (also like me) so you're only out a can of throttle body cleaner and a couple of paper towels.

 

Your idle motor is on it's way out. It will continue to get worse so just replace it.

 

I got a big air cleaner under the air cleaner is a big I do not know Carberator maybe it has two openings and two round plates one in each opening. On the videos I found searching for clean throttle plate I saw a One opening thing with one round plate So you could spray it out and clean it without the spray going down into the motor with mine if you spray itit will just go straight down into the engine I think could you lease explain thannks

 

What motor do you have? 92 was the first year for the magnum so if you have a 318 it's the magnum if it's the 360 then you have the LA witch looks like the diagram below.
