I've had a new tranny put in and this is when my stalling has started before then the car ran like a top. When i first picked up the car it sometimes didn't want to shift into second then i took it back then he adjusted the kickdown cable and about a week afterwards this is when i started having trouble from the engine stalling when cold it will always start right up but i have to keep it running by flooring the gas. It will not even stay running if i crack the throttle body so i know it isn't the IAC plus this is new. But is it possible for the tranny to be stalling the engine out. I will be bringing it in for a diagnose on monday but this idea just occurred to me.
