I have a 2015 Mirage and it just did something super strange. I was reversing out of my parking spot and it was like I hit a bump. I gave it gas and it went nowhere (after it was already moving). I tried again and noticed it was the accelerator seemed like it wasn't receiving the signal to give it gas. I finished reversing and tried to go forward and every-time I went past 25% throttle it would just stop and stay at 25%. I took it out of gear and revved the engine and it seemed to go away. I seems to do it only when it first starts (after cool down, not just all night) and just out of idle. I was also noticing that it has stalled (actually died) twice while idling just after start. Anyone have any ideas? It has 85k miles on it. No other issues.
