Message: [QUOTE="BMAC997.3, post: 1401890, member: 26295"] Hey guys. Been lurking for a while but this is my first post. I just bought a early '99 F250 7.3 6-speed with 200k miles. I've got an issue with my 7.3 and looking for some answers. Researched a ton of threads but can't seem to find anything that helps. The truck runs great and idles smooth after a cold start, but after it warms up, it develops a choppy, sporadic, rough idle....it lopes and misses sometimes. No surging or stalling or anything, just a rough idle that shakes the truck. I have changed the oil and oil filter with no change in idle. Im getting ready to change the fuel filter, but the one thats in it looks brand new. I've checked the UVCH on both sides and they seem clean and secure. I've also unplugged the ICP with no change in idle, ICP also was clean with no sign of oil. I dont have a check engine light at any time either. Truck seems to run great and never stalls, just has a rough idle after its warm. Any ideas? [/QUOTE]
