I have an intermittent problem I need help with. Symptoms: Intermittent issue. While driving constant speed or after deceleration, then pressing the throttle pedal has sometimes no effect on acceleration. It feels like as the engine has stalled for about 2 seconds, before the vehicle picks up speed. This is dangerous on highways and my wife is scared to drive the car with the kids. First I noticed this at speeds 40-50mph or 60-70mph. I am not sure if this is either related to (1) the transmission not shifting into lower gear to accelerate, or (2) if there is no additional fuel getting to the engine, or (3) maybe TCL not disengaging. Recently I also noticed this while driving constant speed ~15mph or ~30mph, then pressing throttle slowly the rpm display oscillates, meaning rpm goes up and down, back and forth. This tells me it is most likely the transmission failing to shift to lower gear. Was at the dealership,  and they said they cannot reproduce this and don't do anything. Probably because it's on warranty. Can anybody help?
