Well, it doesn't sound critical. Your car probably drives fine, it is likely emissions related.

And you can see precisely how much fuel you are using now (just not distance or mpg) so that you can still "beat your high score" for recurring trips by looking at the "current" screen and seek out the route/technique/mod that uses the least fuel. You have an odo and a speedo (and a car) that still work for distance/speed.

I wouldn't be suprised if you could look at the speedometer and the gph and do the instant mpg in your head after a tiny bit of practice. You just divide mph by gph to get mpg. so 60mph @ 2gph = 30mpg. 30mph @ .5gph = 60mpg
