I have a 91 S10 4.3. the truck is idling very erratically and stalling. I replaced numerous parts and think I have pinpointed the problem to a vacuum leak. The sound is coming from behind the heater control and when I pulled it out slightly I can hear it hissing. But I can't get the control all the way out to see better. Could this be the reason my truck is idling so poorly?
