idleing problem

[GoldieStroker944]

i have an 03 7.3 and it seems to idle kinda of rought it isnt really hard rought but it just isnt smooth it seems like it just surges a little bit also when the tach moves up and down the lights seem to flicker also the lights flicker going down the road i had it put on the computer and i cant remember the codes but i was just wondering if anybody else had a problem like this ???

Sounds like it could be loose connections or possibly something like the pcm going out in it. we need to know what those codes where tho.

ok well i know one was an over boost code or something but im not sure i will get it back on the computer and i will post back up the codes but thats what i thought it was a loose conection but yea like i said i will get those codes for you thanks
