Well I replaced the a couple vacuum lines and used some hose clamps and finally idles at 800 perfectly. But...on the end of the BAC...I broke off that electrical plug. Is this more bad news? Frankly I expect it with my luck. I had the car idle for 10 min with the plug off, and it held almost perfectly, so do I need this plug to be fixed somehow? Any help as always is more than welcome

 

Well, if you broke off the plug for the BAC it will only affect if you have the engine under load (such as A/C and P/S) while idling, the idle may dip as you use one of these two things if the BAC isn't operating. Other than that you should be fine.
