This sounds like you have a severe mixture problem.  Since it's doing it
both hot and cold, I suspect that the linkage that goes to the injection
pump from the throttle pivot rod either popped off, or broke off the
plastic end link.  Look between the injection pump and the engine, and
check to see if the linkage is still in one piece and operational.

If that's okay, check the rest of the linkage.  The rod that goes up
to the throttle housing is 2 pieces -- check that they're tightly
clamped together.

Injector cleaner shouldn't make any difference on a tii.  With injection 
pressures in the 400-500psi range, there isn't much of an opportunity
for crud to deposit in the injection system.  Sounds like the shop doesn't
have any tii experience.

Does it run smoothly at a constant speed?  Are they sure it's running
rich?  If it runs okay at a constant speed, and is not running really
rich, the filter and screens may be plugging up.  Check to see that the
electric fuel pump is pumping sufficient volume.

Hope this helps,
