93 Octane

Some datalogs of a fuel cutoff issue. During heavy acceleration, between shits the fuel seems to cut completely off for a split second. Furthermore, from high RPM >4.5K, if I let the engine RPM drop (clutch in, no throttle), the engine will drop down regularly to idle RPM and then stall. symptoms started after leaving the car for 6 days total in an airport long term parking lot, Michigan, Feb5-10 (cold week).
