The 717 was thankfully able to maintain sufficient bleed air for air conditioning/pressurization. Each engine had two bleeds: one low pressure and a supplemental high pressure. Normally the low pressure bleed was sufficient to run everything. At low power settings, the high pressure bleed would open automatically to increase pressure in the pneumatic system. Really the only time I remember having a problem was at low power while running all the anti-ice, even with the aforementioned high engine idle.
There were times that I would consider throwing the gear out, like the Tupolev and other airplanes. It came down to whether you wanted ice all over the gear as well!
