I have a question. I installed a mass air system in my 87, and it has a very bad surging idle with the oil fill tube to T-body PCV hose hooked up. When I unhook it it idles perfect. Could it be that since I do not have an EGR system there is too much gas in the crankcase, which in turn would cause the idle to surge if that gas is going directly into my T-body? IF I leave that hose off, could that hurt anything even though it idles perfect??? Thanks
