I had a code 1443 come up once last week and cleared it, then this week it came back again. I had left the gas cap loose last week but that is obviously not the problem. I've started to check the EVAP hoses and connections but nothing stands out. Any problem child in this system besides vac leaks. Is the fuel tank vapor valve a problem?
