Hey guys i got a 97 4.0 and on friday night and till 4 on saturday me and a buddy put on a det of pacesetter headers on the truck. There kind of a pain in the ass to put on then 2 of the head studs wouldn't come out. Anyways after i out on the headers the truck idles at 1500 and doesn't want to idle down and stays at 2000 if I put the clutchin and come to a stop. then idles down

also the trouble codes come up

what would this be ive been reading other post and everyone has an idea but nobody knows what it is, has andyone had this problem after the headers?

thanks
Cody
