Okay, so the light came on again after a couiple of days so I replaced
the gas cap and the station cleared the codes, I put on 150 miles to
get the computer "ready" and the Jeep passed the emissions test. (The
brakes passed the safety test as is).
Three weeks later the "check engine" light is back. Assuming I get the
same codes this time (0442 and 0455-small and large leaks) where is a
logical place to find a probably intermittent evaporations system leak?
With a specific target, I may try to find it now, otherwise, I'll just
wait until I need the emissions test again next year.

Just to double check....
When you replace the gas cap you ALWAYS turn it until it 'clicks' 3 times
right?

Re: XJ Failed Emissions Test-"It's Baaaaack!"
On some vehicles gas caps from the dealers are better, or at least seal to
the gas filler tube tighter.
On the 2001 you might have pumps, tubing, valves, cannisters, relays that
are for the evap system too.
Maybe you could test the evap system by disconnecting one of the hoses/tubes
and supplying very very low air pressure to it to see if it leaks out. If
it does then listen for any leaks.
Just a thought,

On the 2001 you might have pumps, tubing, valves, cannisters, relays that
are for the evap system too.
Maybe you could test the evap system by disconnecting one of the hoses/tubes
and supplying very very low air pressure to it to see if it leaks out. If
it does then listen for any leaks.

Re: XJ Failed Emissions Test-"It's Baaaaack!"
On some vehicles gas caps from the dealers are better, or at least seal to
the gas filler tube tighter.
On the 2001 you might have pumps, tubing, valves, cannisters, relays that
are for the evap system too.
Maybe you could test the evap system by disconnecting one of the hoses/tubes
and supplying very very low air pressure to it to see if it leaks out. If
it does then listen for any leaks.
