Looks like maybe it's the ECU being glitchy. Also, it might be your traction control kicking in and possibly slowing you down a bit.

Looks like the auto tranny isn't engaging properly, similar to a slipping clutch. Check the tranny fluid and if that isn't it you'll probably need to see a mechanic.

Your slip light is flashing.
Try turning off the vdc, slip light will slow you down.

That is a pick of your dash, not running.
Slip light is picture of the car with the s shaped lines in the 1st vídeo.
Start engine & turn vdc off.
Check your owners manual.

I think your mechanic is confused.

Try turning off vdc like the others mentioned, if it still happens it's probably a tranny problem.

You can't reset the throttle bodies. We do have a pair of them, but we don't use them really. The VVEL system does all of that for us. The throttle bodies just stay opened unless the VVEL system messes up if I'm not mistaken.
