when you start in the morning runs rough sounds like a bucket of bolts. and when you take off from a light has no power dam near have to push it to get across the intersection. but then it will start to pick up slowly and pump out black smoke and I keep it floored and it like once you blow it out it takes off like a raped ape runs fine and its like that all day every day. and that's every light all day. I clean the egr was hoping you could point me in the right direction. thanks
