there are 3, the top hat looking thing as well. the one in front is idle adjustment(biss). one in rear is set at factory, adjustment shouldnt be messed with. the top hat sounds like your culprit. when you let off accelerator it keeps the last of your rpm from dropping to fast and car might die. it lets the butterfly close slower, so iac can work its majic so car will run with butterfly closed. if it engages too soon your idle will take longer to come down. hope this helps, j sin
