RB25 series II, Power FC, stock injectors, greddy intake manifold
Car starts up and idles perfect. However, after driving and getting up to speed and then suddenly letting off the throttle, the idle drops below 900. Sometimes it catches itself before getting too low, but other times it just dies. If I'm coming to a stop, press the clutch, and let off the gas the same thing usually happens. I can usually keep the engine from stalling if I give it a tiny bit of throttle as the RPMs come down. The stalling seems to happen any time the RPMs drop too fast. After stalling, the car always starts back up immediately with no idling problems.
It's pulling 19-21 vacuum at idle. Ideas?
