runnin like S*&%

[colebrian69]

just joined the site after lurking for quite a while. and i hope someone can help



early 99 f250 7.3. runnin bully dog gt, 4" exhaust, 207k miles, DIY intake.

my truck has progressively started runnin worse and worse. starts up and runs fine when its cold, as soon as it warms up the idle starts bouncing around from 650-700rpm and when driving it stalls but doesnt die when letting off the gas. oil changed prob 200 miles ago, fuel pressure is 63 at idle, replaced icp and ipr within the last week. hpop pressure is around 500psi at warm idle. no abnormal amounts of smoke from the exhaust.

im runnin out of ideas and money changin parts that dont fix anything

thanks in advance

Brian

forgot to add that when i unplugged the icp it ran fine no rough idle no chugging when letting off the gas just shifted funny, which with the new icp sensor it leads me to believe the wiring might be bad. but what do you all think?
