Sometimes runs smooth without incident till I come to a complete stop. then runs rough sometimes with an extremely hard shift up. new intake manifold gasket, fuel rail & injectors, distributer & wires & plugs

Have you heard of Noid lights? You unplug the fuel injector and plug these in and they will light up if the injector is getting power. This might give you a better hint. There are also lights that go inbetween the spark plug and wire. Between these two items you may be able to narrow down the problem to a specific system. I believe that your car has a coil pack. Some of these engines have problems with the crank trigger. I believe it is located on the back side of the motor. If you decide to change it, be careful. I have heard of them breaking into two pieces and becoming a big problem.

If you have spark and gas it should at least fire unless you don't have any compression. I would make sure that you have spark on all cylinders at the spark plugs.

2003 dodge ram 5.7L intermittently has a rough idle and an idle rpm of 500 I think the normal is 650. When I put it in gear the idle picks up and smooths out. Sometimes it will do this in gear and stall...

okay, the o2 code can cause problems, theres a problem with one of the o2 sensors, theres 2 or 4 sensors,the repair was not done right or theres another bad o2 sensor, next thing i would check is the idle air control motor,this sounds like it sticks at time or just stops working,start with these things first,

Missfire

Have you replaced the coil yet? I assume by all 4 cylinders misfiring you mean P0300 Random Misfire? It could be a number of other things - a faulty fuel injector, coil, etc. Read this article for more info on random misfires - http://www.obd-codes.com/p0300
