Better late then never, for archive purposes:
It sounds like when your driving without any capacity left in the main battery. The system fully relies on the gas-motor, hence the increased revs... Now this could be a problem with the batteries and/or the electric system, however this should result in warning messages and fault errors. However (I don't know if this is the case here), same 'symptoms' will also occur when its really cold. When summer kicks in, you notice thats the battery has more capacity en sensors will release more power from the electric system. This is not an error.

This is a typical symptom, in autos, of a failed shift solenoid, preventing the trans from finding low gear.
In a manual it may mean your clutch is worn out and slipping.

1 check the 12 volt battery
i have replaced 3 car batteries on my 2001 Prius, purchased in 2001 15 years ago,
that small battery is the primary battery for all onboard computers and must have 11 volts when starting, I noted a poor response when that battery gets week.
2 check your codes with a scan tool or take it to a shop who will read it for free. Note all codes and write them down
codes that start with P3000 and up may indicate something wrong with the Hybird system, common codes like P3011 - P3019 indicates a faulty battery pack.
once I got a P011 and P013 with the master warning was on. It was time to replace the Hybird HV battery. 188,500 miles
hope this helps

It sounds like your vehicle needs a major tune-up. Try putting in some fuel injector cleaner gas additive and a new air intake filter.

Sounds like a timing issue. Was your timing belt recently changed or have you serviced this at all?? I work on these v-6 motors the 3VZFEs and the 1MZFEs. Many mechanics that perform timing belt replacement on these V-6s, improperly set the rear cam sprocket to mark causing offset timing. These engines will still run almost normal(no missfire) or may encounter very low idle and very lowend power, run hot or have a very slow takeoff. Have the timing checked, if offset have an experienced toyota mechanic work on it.

It sounds like you may have picked up some small debris from the bottom of the gas tank when you ran it empty. You may need to run a fuel/injector cleaning solution through the next tank of gas to clear the debris and consider changing your fuel filter too. Sea Foam is a great fuel additive and I recomment trying it full strength. Hope this helps!
