6.0l intermittent rough idle

[SmokedF747]

2006 6.0l elite stage 2's, when idling, after like 10 seconds or so it'll have a slight hiccup in idle maybe rock a few rpms up and down, then idle normal then do it again, any idea? or is this normal? running extreme x and idp ficm performance tune.

happens every time idling, not just every once and a while if that helps.

Its because they have plugged spill ports.

I agree thats twice Ive seen that posted in the same evening. Im positive i dont want injectors with plugged spill ports. Not that it hurts things but just dont want to hear that crap

With the proper tune you won't. I have plugged ports on my 205s and its not as bad as most make it out to be. But as stated with a tune for plugged ports you won't even know they are there...

As far as I know a little fuel pulled at idle fixes it

Why are the spill ports plugged?

Should've asked what are the spill ports.
