so everytime i smog a car on the bar97 when it comes time to do the gas cap test it gives me the error message unable to pressurize and also the message initial reading out of range. so i am unable to finish the test. it started doing it yesterday. i called esp but they havent showed up yet. it passes the gas cap calibration when i do it everytime. anybody have this issue before? the line from the machine to the gas cap adapter is on tight and doesnt show signs of leaks.
