Does this help: When it redlines, the "Check Gauges" light flashes. The "Check engine" light does NOT come on.

No that doesn't help because that is what would happen when it relines, does it do it at a stop then when you move it goes back down? If it does it like that make sure coolant level is full and then check your rad iator for cold spots if there are then it need replacing.
