I need some help. Just been driving my car today after letting it rest for 4 days. Its started to act strange everytime i go to 4.5K revs it feels as though im hitting the limiter and the car jolts. Car is running revo stage 2+, never had any issue before. but now worried it might be in limp mode or something bad is wrong. This happens while driving and is in all gears.
I have added a video to show what happens
