So I'm trying to track down a problem on my 95 pathy. When I start the vehicle and while it cold ( sometimes longer) I smell alot of fuel and I'm getting around 12mpg or less. The only thing I have changed on it is I put on some 31s from the factory tire size. When I take off my fuel cap I don't get any noise, I changed my filter but it didn't help much and I've looked at the tank and saw some spots where it looked like fuel was/is leaking. I noticed the vac line to the purge valve was corroded so I dosed that but im wondering what else I can do to try to solve this issue.
