I am the only one who drives this thing so
I can't blame it on the wife this time . . .
but I did notice that the cap 'ratchets' way
too easily. So I suspect it is not sealing
properly. Never wore out a gas cap before!?

So I pulled the line that comes from the gas
tank and attaches to the charcoal canister
in the engine compartment and connected a
little tire pump to it. With the pump running,
sometimes the line and tank would hold
pressure when I screwed the gas cap on
and sometimes it wouldn't. So that may
be the culprit. Hmmmmmm

Thanks for the ideas, I'll check the other
hoses too. JELo '02 TJ Sport

In any case, limit your search for now to physical leaks and forget about
sensors and crap like that. The code(s) you are getting are the same fault
in varying severities, when you find the gaping hole and fix it, the code
for the minor leak will go away.

You are aware that you can check out the code reader from the auto parts
store and reset the codes, right? At least you can use the code reader for
free in the Once Great State of California, now known as the People's
Republik of Kaleefornia. You can buy one on eBay for about $75.
