Missfire after header install/2000 chevy silverado 5.3
I have just recently installed long tube headers on my 2000 Chevy Silverado I still have the EGR valve hooked to the header but a vacuum line and another egr looking peice for smog I pulled apart not thinking that would cause a problem, the truck is throwing no codes but is missfiring, all cylinders are firing off and each header pipe is warm but it had a rough idle and drives like crap, the o2 sensors are pluged in and everything but could anybody give me some strong info?

i was doing my install and tried to rush it because it was getting dark. finally got it al done and was excited to go go test drive it and it ran like ****. when i got back i had two burnt wires and half the wires were not even pushed in all the way. in my mind i thought i checked everything. sometimes we get in a rush and forget things
