Whats up everyone I have an idle problem I cant figure out. My car is a 92 notch with a 306, Edelbrock heads, E-cam, Cobra intake, 6 pounds of boost etc. My car has always idled best right around 1000 rpms. When I am sitting still in traffic for a long period of time my car will all the sudden just drop idle to around 500 rpms and stay there until I go again. After I drive it for a while and hit the next red light its back to normal at 1000 but if I sit there for a long time again it will drop and so on. I have also noticed that the hotter it gets out side the lower it tends to idle so if I raise the idle at the throttle body and get it where I want it the next cool day I drive it she is idleing to high. I feel like i'm going around in circles. Any help or input would be greatly appreciated
