So, I got a new one of these 3 days ago.  On cold start, it likes to surge and lull for several minutes before the idle straightens out. If it's warm, this doesn't happen.

So I decided to out and record it on my cell phone tonight and instead, it did somethi different: Basically the throttle did almost nothing. It idles around 1550. I step on the gas, and it only gets up to 1900 maybe with the pedal all the way to the floor. I put it in neutral, same thing, pumping the gas pedal does nothing.  I put it in reverse and tried to back out of the garage, and it did nothing.  I put it back in park, turned it off, and restarted it, and it worked.

Are these electronic throttles flaky like this? Or should this go straight back to the dealer?

There has been some bad throttle modules and idle air control valves so yes, it should go back in...IMO
