Odd throttle issue

[mr_miles]

I went to Toyota, and the guy I spoke with was almost reluctant to help me mostly because I think he had no reasonable idea on how to help me, he seemed afraid to help because it's a potential hazard I guess. He asked a tech and the tech said the best they could do would be to go for a test drive and go from there (no shit, right?) and it would cost me at least the regular maintenance fee. I don't have any warranty time left, but he suspects a manufacture warranty would hopefully be in effect. Bleh.


I did notice that while this event is happening, if I put it in neutral and maintain my speed (downhill, etc), it revs up to 4k. If I slow down with the brake pedal, it almost immediately drops to regular idle.

If I use the E-brake to slow down, once I hit between 50 - 60, it force drops to regular idle. It does this if I slowly stop, or stop faster.

I can also force the event by accelerating above 70mph. 60-70 seems to be hit or miss for the event.

I have an idea though! The rear hubs each have a speed sensor, correct? is it possible one could be failing in such a way that is fooling the ECU to think the car needs to be revved? or is there a speed sensor / shift sensor in the transmission that may be causing an issue? I've always noticed upon shifting during normal driving conditions, the car does seem to very LIGHTLY blip the throttle when I shift. Even with my foot off the gas.
