Ok started my car and about 10 seconds later the check engine light started flashing. shut it off and checked codes got 12 (battery disconnected) 43(Misfire) and 55 (end of codes)
Also lately ive been having electrical problems such as turn signals not working on and off, cd player has bad ground.
Checked and cleaned the ground under the hood and now the turn signals and cd player work fine but i found a ground (next to passengers side shock tower) that leads to nothing (pictured below)
Could this ground be causing the problem?
there is also one that looks just like it in the passenger side wheel well that leads to nothing also.
