No throttle response

Had an issue this weekend while driving through Colorado. I went to accelerate and I could push the pedal to the floor and would get no response, no engine rev or anything. I let up a little and tried again, same thing. I had to completely let off the pedal and then it would work fine. It did this twice and never again all the way home to Vegas.

 

I was in sport mode both times and no CEL came on. I haven't had a chance to see if any pending codes have been set.

 

Any thoughts?

Well it is fly by wire...so one theory is the accelerator position did not get communicated to the ECU. Maybe check the connections around the pedal?

Do you have any monitoring tools? I believe the Phone app OBDII scanners can log the pedal position. OBDLink does have the PIDs.

 

 

Nothing showed up and it hasn't happened again. I'm going to chalk it up to momentary glitch for now.
