Granted, mine was flashing the warning on somewhat harder acceleration runs (by no means WOT). I also noticed that it would reduce the power but would not go into limp mode, per se. Warning would be gone upon restart, like yours.

If you have an aftermarket muffler, that's where I'd check next.

Hopes this helps, good luck.
I do but I put it on myself and made sure to plug these.

If you leave them unplugged you loose power
