That link was helpful. Im sure it wont hurt to change out a few sensors, however I paid more attention today tot he issue. Started car and it idled fine. When warmed up enough to drive it ran and sounded fine. I got to my 1st location and left the car running. When i came out it was well warm and the idle was poor. As i drove on the car acted as if running on 5 cylenders and had a rough idle. I got home, parked the car to allow to cool down. I came back out 30 min later and the car was still kinda warm. Started the car and had the rough idle. So i went into work and came back out 6 hours later. Started the car and it hummed perfectly... until it got hot. Acting as if something is expanding/retacting from the heat and allowing a misfire or a vac leak of some kind. I noticed today I am missing 1 bolt to my manifold. Broken off or missing. No loud exahust sound at all. Im stummped.

Do you have a check engine light and also when was the last tune-up??

Try cleaning the idle air control valve and EGR valve and see what happens
