Your the best Merlin!!

I, like many unfourtunate souls, have the dreaded "gas cap code" issue.
For me, it's a P0440, which from your post, tells me I have a gross leak, which makes me happy...it should be easier to find that way......

At this time, I'd like to point out that I suffer from ASEphobia, that is an irrational fear of somebody else working on my truck. I often sit in the waiting room, reading that issue of sports illustrated from 1986 (the one with Icky Woods on the cover), and wondering what the hell is going on in there.

Several bad experiances with professional mechanics in my youth have damaged me for life!!! (a few long stories I won't bore you with)

My question is this, what can the average guy do to seek out the gross leak? I've gone through the whole system, and checked for obvious cracks, loose hoses, and such, but have obviously found nothing. (already put a new gas cap on).

My sending unit is currently on the fritz. My gas gauge goes back and fourth often like an old analog multimeter, could that have something to do with it?

can a bad air filter can cause a P0440 (internet myth?)

Thank you O' wise master of automobile (yeah, I'm sucking up...but I need help!!)
