Engine not idling right

no iscv attached. They haven't been tweaked in any way.

Assuming that the throttles have been cracked open by adjusting the
main throttle stop screw between the two centre ITB's, they should be
reasonably well balanced. As a quick check you can use a piece of
garden hose or similar. With the engine idling, and the filter socks
removed, put one end of the hose close to your ear, and poke the other
end down close to the throttle butterfly.

You should hear the "hissing" noise of air being sucked past the butterfly.
Check each one several times and compare the sounds. If some are
louder than others, they are sucking in more air. Hopefully they will all
be much the same. If not, then you will have to adjust the throttles with
the individual throttle stops until they all sound the same = PITA !!

Oh yeah... and probably not a good idea to use the hose if the throttle
is popping while the engine is idling.
