Re: Check Engine light: loose gas cap LOL!
You should have read that inspection report if you were going to refer to it.
There is a visual inspection of the evaporative controls. There is a functional
test of the gas cap, when it's tested for leakage, as well as a visual
inspection of the cap for proper fit and installation.
The result for the Evaporative Controls Functional test is "N/A".
Meaning: There is no functional test of the evap system performed during the
smog test you're so proud of.
They didn't do a vapor pressure test on your Bronco.

I watched them pressurize my tank, and didn't look at the report.
You are right it came up on the print out as not applicable.

Re: Check Engine light: loose gas cap LOL!
My manual says different. It says to check the hoses and system for
leaks when code 31 comes up. That would include the gas cap....
I will believe the book instead off 'bllsht' any time... LOL!
