Attention: TDR Forum Junkies 
Truck hesitates or stumbles when cold leaving light. This is Florida cold not Michigan cold. Stumbles go away when engine gets to operating temps. Also for a few days motor would just shut off when go pedal was lifted and rpms dropped back to idle-tach would show a stumble then motor would shut off. Slap into neutral and restart. This happened for a couple of days in a row and then dissappeared. Anybody got any ideas?
