Inconsistent Rough idle, already replaced multiple items
Hello i just joined this forum hoping to obtain some insight. I have a 2000 Dodge ram 1500 5.9L 4x4 with about 111,000 miles. I bought it in January or 14.
Issue: I am not sure if it would be considered a miss fire but at idle it goes rough than smooths out, than goes rough again and than smooths out etc etc. Not horribly rough but still enough to feel.
replaced: I have already done the cap(mopar), rotor(mopar), ignition coil(mopar), wires(bosch), plugs,(NGK), IAC(mopar), Plenum kit(Hughes), K&N Air filter, Hughes Thermostat, PCV(mopar), belt & tensioner(mopar).
I saw people saying the TPS possibly but if i wiggle ithe connector while running nothing happens and normally if that is bad moving it will kill the engine or make it bog.
Any theories?

Did u scan the comp? You may have an engine code even though your eng light isnt on--check the vacuum plugs/caps and lines very well disconnect ur tps and see if it makes a dif it is also possible you got a bad idle air control solenoid even though its new--Check the fuel pressure-shrader valve is easy to get to--what u are describing in my experience (no codes) has been a bad iac-Fuel issues usually set a lean code-and tps etc almost always set a code-
