i know i have a leak somewhere. i noticed earlier that while cruising at about 60 and 1700 rpms air comes through the vents with them off, then a slight increase in throttle makes the air stop, then when i let off the gas at the top of the hill i feel a stronger burst of air. the burst is about 1/4 as strong as when the switch is on low on face/feet.
what are the two canisters under the dash with the red and yellow vac lines on them for? i'm thinking that they have something to do with my issue (actuator doors maybe) but i may be wrong, i've never chased down a vac leak before.

honestly,
Vac leaks can be a nightmare to track down. Your best bet is to go to a shop with a smoke machine that will send smoke thru the vac system and identify the spot of the leak.
You can also try to cap off and isolate each system from the tree and see which one improves the condition, just don't take off the big one that goes to the brake booster or you'll be hating life.

well i'm pretty sure i found it. and i'm starting to think that the guy that did my transmission is absent minded. he used a rubber seal instead of the oem rubber/plastic one that i wanted on there (i even had a new one in the back seat). he had the transmission bolts too loose, it took a little over a half a turn to get them all to 13 ft lbs.
and he left this on top of the heat shield over the cat:
but i found out where it goes when i stuck my camera above the transfer case:
now i want to drive it to see if the vents will work right but i need to get the front end back together before i can.
do you think it would have any ill effects not having the vent or the vac lines on the transfer case for about 1000 miles? and do you think i could get away with strangling that guy?
