Just reading through this thread I've learned a lot about my AT that never knew before.

Would this affect fuel economy?

That delay is normal in auto's since all new cars have the Drive-by-wire technology.

If I'm correct the way it works is:

->>You step on the accelerator
----->>Accelerator signals are sent to computer
-------->>computer regulates gas going into engine
------------>> car moves.

It's safer and more efficient than the old quick direct metal line throttle response from accelerator.

Old style cable response is immediate since the link between accelerator & throttle body is a cable. New style drive by wire has a delay due to cpu processing & translating the TPS and commanding the throttle body opening. Nowadays the delay is shorter due to faster cpu but delay still exist.
