I have a 2012 Malibu TXI and have experienced several throttle glitches. While cruising at 32-34 mph with Zero Off disengaged, the engine will suddenly reduce throttle to idle. I put the throttle into neutral and re- engage forward and everything seems ok. It has happened 3 times in the last two weeks and today it happened repeatedly while returning to harbor. It has never happened in the slalom course while Zero Off is engaged. Anyone else experienced this? I am wondering if it is a bad connection in the electronic throttle assembly. Taking it in this week to have it looked at.
