    Stalling in colder weather

    So it was a bit cooler here in Florida that past few days, overnight temps in the mid-to-upper 30's. Cold start and drivability in the morning is fine, only real issue I noticed was that sometimes before the car warmed up and I slowed down for a speed bump or to come to a stop, it would overshoot idle RPM and stall. Because the car bucks at those RPM's when slowing down, this is a clutch-in, brake depressed behavior. I logged my RAF and the STIT's from a cold start were between -1.5 and -2.5g/s.

    Since these cold mornings don't happen very frequently it's tough to test changes. Any thoughts on what I need to log to see what's causing the behavior?

    I didn't look at your file, but curious to know what mods? E85 is one thing that comes to mind under cold start. My Camaro is difficult to start in the cold and runs on E85.
