i have an '82 wagon w/ the b23e engine & the k-jet system, thought i'd try taking off the tbi to do a cleaning like in the instructions given for the LJ-jet on ipdusa.com's website, however after removing the throttle linkage & unbolting it, it wouldn't drop down. it flexed downwards, but still seemed to be retained by something. i couldn't get the large hose off the backside, but i assumed it couldn't be all that was holding the tbi in place. beyond the 3 nuts, is there anything else that keeps it in place ? what about cleaning the MAS unit at the bottom ? it had oily sludge in it as well, but i didn't want to prod into it too much for fear of damaging something ... this is my first car with fuel injection, so i'm a little worried about breaking some little expensive parts. any info on tuning/cleaning the k-jet system ?
thanks.
this board & the users really rock, i can't imagine finding anything like this for any of my previous cars =)

There are four bolts(one way back there).If you put a little more force on the hose it will pop off(given there isn't a hose clamp).Get a new TB gasket also.Clean it really well with carb cleaner and an old toothbrush.Don' try to clean the MAS too much, but do clean the bellows and hoses attached to the TB.
You should have a smoother idle when done.
