Hey everyone, so I have an embarrassing issue regarding normal acceleration from a full stop in Tour mode. I have noticed this hesitation when taking off from a red light, stop sign or even pulling out of the garage. My thought was a defective Mass Air Flow sensor however, I pulled things apart and cleaned the MAFS which resulted in NO CHANGE. I also noticed that this issue goes away if I switch over to Sport mode. When I purchased this C7 new I didn't have this problem, currently I have under 16K miles and stored in a climate controlled garage. Anyone have an idea as to what else could cause this issue?

i had the same issue when my plug wires worked loose,
could it be something with the throttle mapping, since the inputs might change to the throttle body when going from tour to sport,
let us know if you figure it out

Many thanks my friend. This scenario seems a little strange In that I do not remember this earlier ( months after purchase ). I will inspect the condition of the spark plug wiring before taking it to the serv department. Let you guys know about the result.
Well I did not know mine was loose and replaced the MAS then found the wire was not on all the way, best of luck
