OK last Sunday afternoon after slowing down almost to a stop then idling up to a red light my truck felt like it was fixing to shut off for a split second. Then the EVIC showed a message or the throttle valve service soon. Ran fine since then up until today. Pulled into a parking lot and backed into a spot.
While waiting for the exhaust to cool it did the same thing again. It sounded like the exhaust brake was kicking in both times noise wise. Truck ran fine on the way home. Before I left the parking lot I looked for a DTC but didn't see one, unless there is a soft code I couldn't pull up?
2015 G56 Raceme Ultra.
Full delete except for the throttle valve (it IS unplugged and has been since deletes done at 36,000 miles). Have 134,+++ miles on it. Oil and all filters have been changed, always before they are due.
