"dead" accelerator

I'm curious if anyone has / is experiencing this odd symptom. I have an 09 Tacoma TRD Off Road 4.0 V6. Occasionally, upon putting the truck in drive my gas pedal behaves "dead". In other words, it is not causing the engine to increase power and move the truck forward. Instead, I sit there and continue to slowly push the pedal and then all of a sudden it "takes off". Now, the time is very little, maybe a second or two. My dealer said this is due to the transmission not being up to temp and that the computer senses this and does not allow acceleration. But this happens randomly, when cold or up to temp. Any ideas?

 

It could also be a hesitation with the throttle by wire......

Same as if you're driving along normally and want to pass someone and you stomp on the pedal.....there's a brief delay before it actually does anything.

 

I vote for throttle by wire problem , maybe dirt/gunk in the contacts causing problem.

 

i also think your dealer is a retard.

 

Does it do it in park as well?
