hi guys thanks for taking a look wondering if anyone can point me in a good direction. i have a 97 f150 4.6 160k miles. so my problem is after the truck is fully warmed and sitting at a red light for a little bit the truck begins to idle very rough and my exhaust then smells like some one ripped ***. the idle issue only happens say after sitting for about a min or 2 and not at every stop. then it begins to idle like crap for maybe 30 seconds then it evens it self out and returns to normal idle i have no check engine light. other than that the truck runs great

 

Sounds like your cats are plugged and your o2 sensors need replaced.

 

that would make sense cause they also rattle like a bitch

 

yep there probably deteriorated badly.
