Another fun item to add to the mix - I just noticed after another drive through the neighborhood tonight with my gf (gotta show off the progress!) that the fuel gauge and temp gauge are now pinned to max - Any idea what I could have done running comp test and changing plugs?
Gauges were reading fine before (and I think right after...?) the test...
EDIT: Also realized the panel light is no longer working, which was also working previously. Can the two occurrences be connected?
You probably have a bad ground to the panel. Try running a jumper wire from the panel to a good ground and see if that helps.
