idle rough in dodge ram 5.9L 360 ci please help
Dunno ok guys i need help here i cant seem to figure out whats wrong with my engine its a dodge ram 1500 5.9L 360ci gas engine, usually once or twice a month usually only once then it will go several months with out doing it my engine runs rough, it will idle rough and then for the most part it will drive fine but every once in awhile while driving it it will surge in rpm's when it runs rough. It cant be my spark plugs, wires, cap or rotor because i change them every 6 months and i dont get the cheap ones either, if i could get some very good possibility's as to what it could be that would be awesome thanks.

I would atleast check all that just to make sure. And if its not that then try sensors like crank position and cam position sensors.(witch i don't think is your problem.) Also bad 02 sensors might have something to do with it. But check the wires and plugs first off! They may have failed... Also is your truck throw any codes? if it is find out what that is it will help you pinpoint your problem.

might be the camshaft postion sensor...sits inside the distributor....ive cleaned mine before and solved the same problem...might even need replaced....just my .02...worth a try though

In my limited expierence, intermiten (ya I flunked spelling) problems are often linked to bad grounds.
I wish there were photos to show you where they all are, but spend some time with the hood up and check them all.
A twenty dollar Volt-ohm meter from China Mart will help you eliminate this as a source of problems.
Use only a high impedence type = still only $20

when EXACTLY does this occur? You said while driving, but on the highway, at stop lights, between shift points, etc etc? Does it run rough as in studder and stumble, almost die and then rev high to keep from stalling? Need more information....

the surges occur on the highway only and it only jumps a couple hundred rpms ill be running on the highway at 1600 rpms 60mph and it will sure to like 1800rpms and then back down to 1600rpms. the rough idle can be felt through the whole truck something like a studder and stumble but it doesn't almost die or anything like that. the rough idle at its worst is when im parked the rpms dont fluctuate at all or anything at idle the engine will run at 800 rpms and its very responsive once i step on the gas.

Check tps, common problem on chryslers. My 01 dodge ram 1500 with a 5.9 started idling weird once and a while and thats what it ended up being. Bad ignition components would be more of a constant skip not an occasional one.
