How old is the battery? Can you swap batteries with another vehicle?
battery is a year old and the problem came on all at once so it sounds electrical to me. All the grounds are good and I went through the vacuum lines as well, there are no leaks.
I have had a gascap fault for some time that I didn’t pay much attention to because it was just a gascap — it’s gone now. What put me on the computer is that it is choking out AND has a random misfire AND has codes that don’t make sense (Knock sensor, evap, etc)
