This has to be a huge coincidence but I was trying to wire power to my boost gauge, stopped because I needed a female connector, and the car freaked out when I cranked it up. On the dash, Hill Start Assist Unavailable appeared, followed by Service AdvanceTrac and See Manual. CEL is on as well. Literally all I have done is check which fuses are accessory powered. I did play with the restraints control module fuse but the fuse itself is fine unless I damaged the housing or something? I disconnected the battery and reconnected it a couple minutes later, same thing but I thought I might drive it a mile or so and see if it went away and the throttle started working independently of my foot :/. Any ideas? I am going to run home and get my tuner to pull codes in a minute.
Also, by disconnecting my battery I wouldn't lose the current tune, would I?
I think the wheel speed sensor might have gone bad on me and it is just a coincidence with the timing but I don't know.
Edit: The only code was P0300: Random/Multiple Cylinder Misfire Detected. Not really sure, I guess when the car tried to rev in neutral or something.
I'm getting it towed tomorrow and a good electrical guy is gonna take a look at it.
