According to vacuum gauge im holding steady at just over 16 at idle. I sprayed carb cleaner at every hose end and no difference in idle. On the right side of engine i have fuel regulator and pcv valve and on left side i have brake booster and the other is plugged. Front is plugged too. Plenum looked great.
