Hey everyone, I need some help. Can't pass emissions. I'm running rich because my idle is about 1400 RPM. My idle speed microswitch did not seem to be working, so here's the catch: When I unbolt it from the car and press it, my car idles right at 770 RPM, perfect. When I reinstall it, 1400 RPM. The throttle arm screw is adjusted perfect and pushes the idle speed microswitch down when you let off the pedal. Even if you push it by hand or with a screw driver, when it is bolted to the car, high idle. When not bolted to the car and you push it, perfect idle. I have even tried a new switch AND one working on another car....same symptoms. WHY?!? This makes no sense to me. Anyone have any ideas on this one?
