Bad evap cause bad mpg's??
Man my car has been getting shitty mpg's. Warm, cold weather don't matter. I changed plugs couple days ago and still shitty shitty mpg's. I have 2.8,60's. Basically the zzp s3 kit. Had on for 10,000 miles and the mpg's getting worser. I drive amd sometimes it says check gas cap on the dash readings. Changed the cap and still sometimes says that so now I believe its the evap surge sy. So my question will having an bad evap cause bad mpg's?
