Jeffrey, Try this tool: https://www.nexusmods.com/skyrim/mods/12801/ This is a texture optimizer for the game Skyrim, but I have been using it for years in P3D with great success. It's fully automatic, works with DDS files and has plenty of options to choose from, and it creates backups of the original texture before processing. I have used this on my E170/190 as well.

I can confirm that I am also having this issue. I just purchased the E170/190 yesterday. During flight, using a third party weather engine, with the autothrottle on, any turbulence or changes in wind speed will cause the autothrottles to increase or decrease rapidly in an effort to "compensate" for a disturbance in airspeed. This can be seen both on the engine display and by the throttle levers physically moving. I thought at first it may have been a setting withing Active Sky with live weather injection, which is what I use for weather. To check this I switched from Active Sky back to the default heavy thunderstorms scenario. The autothrottle issue stopped using a default weather situation. So I tried another third party engine: Rex Weather Engine included with Skyforce 3D, also using real time weather injection. My results were the same noting erratic throttle behavior using a third party weather engine vs. default weather scenarios. This is for both the E170 and the E190.
