Stumbling on a hot day
2011 IOM GS with 96,700 on the clock. Car runs great in cooler weather. Yesterday, on a caravan with other Vettes, the car started to stumble at stop lights. Had to shift to neutral to keep from stalling out. Car is A6 and yesterday was 95 degrees. Thoughts? TIA

Maybe dirty throttle body or MAF sensor ??...you need to look at live scan data to see what's happening without having to guess....when was the last time both were cleaned ??
