'96 3.2L -My mechanic friend checked both solenoids and said that wasn't the problem. He thinks it is a leak somewhere in the system. Emissions passed somehow, but the code came back and I am wondering whether it is just a leak or some electrical issue with the EVAP system. Gas cap is good and I want to resolve this in case there is any effect on gas mileage which I think there may be. Any similar cases that were solved?

huh? Can you reply to your first post or post a link to it here?

What do you mean?

What year, what engine....

Oh yeah, it's a 1996 3.2L

I have alldata and a scanner, just thought someone had a solution since there could be many things causing this.
