Prolly not your EGR valve unless it's stuck open. The EGR valve shouldnt open til WOT. Try to see if it happens when all that stuff is turned off then start from there with each componet.

do u let the car warm up first.....my car hates runnin right when i wake it up......kinda like me.......and if u put all that load on it when its still cold it will have to work harder......it takes power to make power....and when the engine is cold its not making all of its normal power.....just a suggestion........does it do it after its warmed up or later in the day......
