No unfortunately not, I've actually driven primarily on the highway since that time as I drive 30 our of 35 miles that way to get to work. Also I know it was not disconnected because it still had the mileage from my "B" trip odometer on it.
So I just had my head gaskets fixed because I was told by multiple shops that they were leaking. Well everything generally seems to be running pretty nicely since the repair I am having a couple issues since this repair. I have the base model 2.5 subaru Legacy from 2009
1. The fuel mileage has dropped from around 26-27mpg on average to 22-23mpg on average
2. There seems to be a different smell coming from the exhaust.
These repairs were finished 2 weeks ago so I don't know if there is a break in period for some of this stuff or not. Just looking for some opinions as to whether I have something else going on here.
