Listen or feel for a clicking coming from the purge solenoid. If you checked everything else concerning the code 0443 it is most likely that it is the ecm!! At any rate, dealership advised that the solenoid was bad again, which I emphatically emphasized that it was replaced 3 months, but decided to tell myself that it could be bad again. It means a large leak has been detected. Re checked the 21 fuse, found it burnt out so I replaced it. I am guessing this will be the same next time I bring it in, but could be wrong.

I'd rather not bring this car to a dealer, but if my mechanic is unable to determine what is going on with it, I believe that might have to be the path I take.

That would've left me without a vehicle until receival of the new part, which would've been a major drawback. You may try removing he relay, cleaning it and put it back and see if things change. Is this a correct assumption? Looks like what I am seeing on Rock is the service to have it rebuilt or something like that. Seems to be a bit beyond my capabilities.
