Idle surge

  • 1982
  • 911 SC

Ok so I've got an 82 sc that has started having a bad idle surge when it warms up. Here's what I've done so far. Replaced the o2 sensor, checked for vacuum leaks as far as visually and spraying carb cleaner around the injectors. When I let the car warm up I can unplug the lambda box and it idles fine. I'm trying to avoid spending the money on a gas analyzer. Or. Should I just disconnect the o2 sensor all together and re-tune the car without it?
