Hello, I think you have a throttle position sensor failing. To test it you will need a lab scope.

I hope this helps.

The only thing Jeromy is that the engine check light does not come on.
Toyota Mechanic: Jeromy Madison,

I understand there is no check engine light. When this occurs the check engine will not occur because the issue is that there is a spot in the throttle position sensor that is bad and most likely only at one speed. I have seen this issue many times it is very common.
