Weird Electrical Symptoms
So I’ve had my 2005 for almost 2 months now, and I’ve noticed every time I give the car ~50% or more throttle, coupled with my right turn signal, I get an error code for my front right blinker. My right signal will then blink quickly like there’s a bulb out. The next time I start the car the problem is gone, but as long as I continue driving after the issue, it will continue. I’ve found it very strange but not too worried since it seems to always resolve itself when I shut the car off. I’m not too electronically inclined so was curious if anyone has any ideas or if it’s a common issue.

Have you checked your front right blinker? Is it possible that the bulb filament is hanging on by a thread and that when you hit the throttle and energize the bulnb the bulb "burns out" but is able to make contact again after cooling down?
Start simple (cheap). Replace the blinker bulbs.

As a process of elimination, I would first start by replacing the turn signal bulb, since it's very cheap. And the next thing is to have the car diagnosed, with a Star Diagnostic computer.
