ok.... since i got the car its had this problem where the vapor pressure in the fuel tank is really high... no check engine codes other than for egr but i am wondering if anyone has ways to test the purge valve and the canister vent valve... im suspecting that one of them isnt working because the pressure that comes past the cap upon unscrewing is way too high and it doesnt seem normal.. if anyone has diagrams or anything that will help test will be great
