06 6.0L idle jumping around

Hey guys
The odd time when I am in traffic or I pull up to a stop light and the truck drops to idle it sometimes jumps 100-200RPM from idle. If you press the brake pedal light enough the rig will actually move/jump well the idle is jumping around. The engine is completely stock with no tune. Only thing I have done recently is I have installed the blue spring for the fuel return. I have no CEL coming on well this is going on. Any ideas??

Unplug your icp sensor it should be on your valve cover and see if it runs better, if it does you need a new sensor or if there is any oil on it you need to change it also. Also inspect the pigtail and wiring going to it. Hope this helps

Idle is controled by the pcm. You need to read pcm values to see what is changeing.
