03 chevy express 2500 stalled

[MT-2500]

Have you got in to the camshaft retard reading/setting?
Some times it is under cylinder missfire section.
If so what is the reading you have?
You need to turn the dist to bring the reading in as close to 0 DEGREES or as close to - or + 1 degrees as you can get it.
Turn the dist a little and then speed the engine over 1K rps for the reading to reset.
If the reading raises up turn the dist the other way.
It will not reset on the scanner reading at idle.
Speed up engine to recheck reading

doo you mean 1k RPM.. RPS is pretty fast.. sorry just to make sure i don't have to like red line it.. haha.. and btw no tach on that vehicle.. but could probably see it on the scanner..

I don't have mcuh chances to bring the van into the shop because it's constantly being used.. right now after the tune up.. it sometimes stalls when it starts but right after that one stall you start it .. it's fine it runs..

I tested it once .. when it's cold it runs very very smooth.. but when it warms up it starts to go rougher .. but not rough to the point you will be like..PULLING over.. it's just shaking a bit at idle.
