If for nothing else, unhook the battery and let it sit for a bit. It’s free and should take 10 minutes assuming the battery is accessible. Maybe it’ll fix it, maybe it’ll get it to finally throw a code/light, it might (probably) won’t do anything, but what do you have to lose?My car just feels terrible now and I can't stand driving it. Different with the new tires, maybe 'better-ish', but still just as terrible. Driving in a light drizzle this morning felt like the front tires weren't touching the road. I have no confidence in it at all anymore.
I don't have the space, tools, fitness or patience at this point to start tearing into it so off to the dealer it's going. Here's a kidney, Honda. Just diagnose and fix it properly.
