Lean long term fuel trims

Just did a quick look over of the engine again to see if I missed anything. I noticed a slight hissing noise coming from the connection at the PCV valve.  If i press down on the connection, the hissing goes away.  When i let off, the hissing comes back.  Possibly a slight vacuum leak there throwing my trims off?

Can anyone confirm if they hear anything similar from theirs?

You're getting 15 ltft at idle for both banks?
 
Check the Fuel Vapor Solenoid especially if original! something to consider especially it playing such an important role plus being cost effective. Z

Why don't you cap off all vaccum and see if you see a significant difference in stft

Won’t matter...any air that is or would escape the manifold would be unmetered air

Are you talking about the purge valve in front of the engine mounted on the manifold?
 
In unrelated news, some old guy that could barely see over his steering wheel, in a 30 year old jaguar, backed into my car today and dented in the rear passenger door and quarter panel.  I wasn't even in the car at the time too.  Good thing he didn't just take off.  Valet guys had to come inside and tell me some guy hit my car.  First accident it's ever been in after 160k miles.  Such a pain.

^^^ x2.  The other gentleman probably thought the FPCM was at fault ;). Hope they find no other damage ...
 
It's not really too much damage, but the door is dented in pretty good and probably needs to be replaced and painted.  Probably going to cost at least $2000 or $3000 worth of damage.

I'll give the guy credit for not taking off.  He actually went out of his was and told the valet guys what he did when he could have easily just left.  No one saw it happen but him.  I could have easily just come back to a car with a giant dent and cracked paint.  Accidents happen, I guess.

All fixed up.  Damage wasn't terrible after all... estimate was $1600 and his insurance covered all of it.  Was actually surprised it wasn't more given how crazy body work can get.  Took about 3 days to fix up and it's back on the road again.  Good as new.
