deep water now no codes
Had to run through some pretty deep water during a bad rain store yesterday. I could feel the water under my feet and a little got in the door. I was able to drive 20 more miles to work bur noticed that it was running pretty rough when I got there.
It started when I was heading home but felt like it was misfiring. It died before I could get to the end of the block and now won't start. I tried to check the codes but it only flashes 12 over and over. The check engine light is on.
Before i just start replacing sensors can anybody think of what this could be? I was thinking O2 sensor because it is low to the ground but wouldn't it still run if that was the case, or at least get a code?
