My truck is surging 2 to 4 hundred rpms at idle and low RPM's. It does it when its cold and sometimes when its warm. Its an 05 6.0 with 40k on it and the only mods done to it is i cut the muffler off and turned it down right behind the cab. I did a search about it and some post similer to the problem but didnt realy get a good answere to what was causing the problem. Could somebody let me know what could be causing the problem. Thanks
