I too am having the throttle problem,

04 auto

I have a blind corner that my street connects to the main road and so I am forced to make quick actions and when i have to go 0-45ish the peddle likes to randomly stick and make my morning even that much crappier!
I have had it so bad one day that i was driving on a fun road at about 60 and had to slow for a turn... nope the car wanted to go faster. I slapped it into nurture and it red lined! had to kill the engine and restart to fix the problem.

My understanding of the throttle on this car is that its all electric, controlled by the body and ECU...
i am currently having a few other problems that could be related.

- for about 6 months now I have had a BAD shake in all gears when between 1,100 and 1,700 RMP.
- when cold and just started the car will drive for a bit, then when coming to a stop... IF IN D or first gear ... it will want to stall out like im not getting enough gas/ or the torque converter is having problems.
-- related more to the last one -- when the car comes to a stop it will rock back and forth like again when a manual is down shifting and its not enough gas...


to counter most of this I have been using the slap stick to shift naturally as possible when slowing down...

Any help in any area would be great!
