Go back to basics, it sounds like it probably has a straightforward problem,
such as a dodgy plug, lead or maybe even an air leak (particularly the last
because of the indicated idle valve fault) Possibly a damaged or burnt
valve or compression leak between cylinders.
The electronic stuff is in my opinion very reliable in general, but people
leap on it without sorting out the basics first.
The clock lights are meant to dim with the lights put on, so they don't
dazzle you at night.
