Lately I've noticed my car has had a wonky power load problem. If I use anything electrical my engine revs up to 1500 rpms, I mean legit anything that has to do with electricity. My windows my AC/heater headlights. Also I've noticed while decelerating it revs up a lot higher but it feels like it has shifted to a lower gear before it should have and it feels like it's using the engine to slow down
