remove tb
remove gasket
make test gasket
block the big hole here. IAC bleed
there are 5 small holes that must always be blocked, (called drillings)
then the slot must be filled. and blocked
we see if engine stalls. it must stall. there is no air now. for sure.
it will tack right foot to get it to start at all (press right foot say 5 degrees?
if it stalls, cut the IAC bleed hole back but not slot hole.
if it still stalls, cut the slot hole, bam? 1200 rpm:"
if yes the slot is leaking some way
do not block H2O

clean and new.

those 5 hole small are drilling, and must never be open.
they drill these for the internal system and a gasket is way cheaper that lead plugs. (lazy bums, lol)
