Thats right I unhooked it. I left the sensor plugged in so I woudnt get a cel from it and disconnected all its vacuum hoses and plugged them. Then I adjusted the idle with the throttle body screw. Its so much better now... Before it would return to idle then bouce up about 500rpm the bounce back down to idle (sounded terrible). That crap is gone now, straight to idle. Cold starts arent an issue... Sounds/runs smoother!
