Re: XJ Failed Emissions Test
The gas cap is by far the most likely cause of your problems. By far.
They can test the cap to see if it holds pressure, I don't get why this
would cause a failure at the smog station. If the cap is bad, they are happy
to sell you a new one for more than double the "street price" and reset the
code and move on.

Re: XJ Failed Emissions Test
Have you ELIMINATED the gas cap yet?
The gas cap is common to both codes, and is by a wide margin the most likely
source of the codes you got. You MUST eliminate the gas cap as the source
before you go any deeper, or you will be wasting both time and money. If you
went out and bought a locking gas cap to keep ********* from stealing your
gas, then the cap is the cuplrit. I've been told by at least two smog
testers that locking gas caps frequently fail the pressure test that they
put the caps through.

Re: XJ Failed Emissions Test
I'm not sure I'd be quite that strong. It _could_ be another problem, but he
won't know for sure until he makes sure the gas cap is not the fault. Given
100 chances for failure, the odds are good that at least 95 come from the
cap, the other 5 come from a cracked hose. Since we're discussing an '01,
I'd take bets that the hoses are in good condition.
