Someone please comment on this. I went from a struggling idle that would die if I let up on the gas, to a roaring 1+ RPM and practically double the exhaust force just after popping out this little valve and spray cleaning it with carb cleaner, and snapping it back in. I would have never expected that in a million years. The only problem is my muffler is now popping constantly. I have my O2 sensors disconnected because I was testing them (they are rusted in and I don't know if I can get them out to replace) but they were out before everything was exactly the same. I'm completely amazed that this little valve did this. Maybe its stuck open now?
@e.gadd.1 vacuum leaks and/or lean mixture conditions can create weird idle and surging issues. There are plenty of videos out there on how to check for vacuum leaks. Heat works with O2 sensors......there are videos on that too
