i removed the plastic completely make sure to clean the vent (if the battery was replaced more then likely it is all ready clean)Hey there,
The symptoms youre describing are the same that we had when our 2008 hybrid 300V battery pack was shot. The batteries that go first are the ones in the middle of the pack. I confirmed this by calling a local hybrid shop and they had the software to read the voltage and load on the pack. All the wierd quirks went away with a new pack. It was about 2200 bucks back in 2016. The only time we see high revs now is after some time and the pack is warm. Were in Las Vegas so what I did to help air flow to the pack was to cut slits in the plastic under the middle row on the driver side. Yes you hear the blower a little more but it can actually move more air that way. In theory will extend your battery life by keeping it a little cooler.
Also the surge or stalls are caused by the AUX pump Controller Date Code of 089-11-XXXX older ones have the issue
