MPG dropped by half.. Scangauge issue?
Overnight, my 1.3l Metro's fuel consumption has doubled with no apparent difference in any functions, engine noise or visible fuel tank gauge change.
For example, the idle GPH went from .20-.22 to .43-.45. The AVG MPG form 48-52MPG to 29-31MPG.
About 2 months ago, Scangauge was giving some other wacky results, much more efficency than before, 130MPG was not uncommon and idling at .15GPH and less. I unplugged it and reset it to "normal" readings.
