Better gas mileage with error code!

Bakerkj · **Posted:** Sun May 21, 2006 4:55 pm

My gas milage went up from 15mpg to 19mpg this week.
I'm also getting an emissions control error code P 0455.
I'm not going to fix it, since it is increasing my gas milage.

Has this happened to anyone else?

Code P 0455 is EVAP system large leak,meaning you have a very large EVAP leak so naturally your not useing the EVAP system and getting better mileage(like taking off a mechanical fan and putting on a electric fan,your vehicle does not have to work as hard).

Had the latest flash done on my 05 Sport CRD the result two days later: P0101, P0401, P0299, P0101, and P0401. Any ideas?
