Well I'd say move to Tennessee. They didn't do any type of testing for that and you could drive the car forever and it isn't going to affect anything. That's what we do here in Tennessee. Now if you want it fixed, you're going to have to find a guy like me who knows what he's doing. It's a very expensive scan tool who can do bi-direction and old testing of the system. It can be in the wiring. It could be in the computer system. It could be a leak anywhere in the EVamp system which goes all the way from the gas tank up to the front of the engine. My advice would at least have a mechanic do that testing and hook up a smoke machine to see where smoke is leaking from if it's got a leak. Obviously you have been dealing with idiots who don't know how to work on the car if they were real mechanics. They do what I just told you and they would have found the problem without just guessing with parts
