Why, YES, the RED throttle icon, WHICH HAD NEVER APPEARED BEFORE (this important information was given in a PM), IS, most likely, very much like a check engine light, which, usually, is ALSO RED, except, in this case, it means to CHECK THE THROTTLE.
Hence the questions about getting wet, crashing, bumping, or falling over. If wet, blow it out, you can even whistle at it, you know how to whistle, don't you? If crashed or bumped, check the wire for loose connection. Do NOT make me repeat that three times.
