im gonna throw this out there...
if air can make it past your TB when your foot is off of the gas, you have an issue. the TB makes basically a perfect seal. in my toyota manual it says to check the throttle body, hold it up into the light, if any light seeps through its bad.
another thing to note. IF the TB is ruled out. the open valves also wouldnt mean anything. simply because after the valves are your pistons in the cylinders. pistons/piston rings are known to have a 1-3% (perfect) and a 4-6% loss at normal use.. meaning your rings never ever make a 100% seal...
meaning.
if you do have a leak, there is a 90% chance its before your TB or at the TB itself.
