So I've been having periodic probelms with my car dieing. When idling it will just shut off when the fans turn on,not everytime but if not pretty close. I tried bumping the idle up with the set screw on the throttle body, it worked for a few seconds but guessing the ECU adjusted it back to 650 or so. The engine wants to run at what I set it at as everytime I start it now it goes to 1000 for a few seconds then works its way back down. So really is there any way to bump the idle with out tuning? YAY GM crap flash lol
