The pickup coil or wear in the upper dist shaft bushing can cause a low rpm miss/stall with the TBI engines.

The pickup coil signal is converted from an ac signal to a dc signal. This dc signal is used to fire injectors and spark plugs so it is pretty important. If the pickup coil is bad, this signal is lost and a miss occurs.
