But all displayed item from bottom panel is item from the 80s and 90s though, so precomputerised kinda either mean carburetor or primitive ecu that only control very limited function and can't scanned with a scanner tool, which is still imo bad. As an automechanic I certainly doesn't want to go back to scratching my head trying to figure out what's wrong.
Edit: not to be too pedantic about it, but that's what i get from this comic.
