I have a 91 camaro 3.1L v6 and when it idles and when coming to a stop it is drops below 1000 rpms and bounces like its trying to die. My friends say it smells like its running rich. I have replaced the TPS, EGR, MAP, IAC, checked for vacuum leaks and if the fuel pressure regulator is leaking. Now im stumped......
