[s-cars] Fuel Injector Problems

OK guys.  This one has got me totally puzzled.  This is on a '91 200 20
valve but all experience here is applicable.  I have a problem earlier this
summer where an injector was "hung open."  i.e. it was allowing fuel to seep
through even after the ignition had been shut off.  I replaced the injector
with a new one.  Now the new one is having the same problem not more than 40
miles later.  All the cylinders are showing signs of running rich.  Is it
possible that they are running so rich that the fuel injectors are getting
clogged so badly that they are "hanging open"???  Has anybody got any ideas.
BTW, through some wierd coincidences the injectors, the old bad one and the
"new" bad one were in two different cylinders, 4 & 5.  I am at my wits end
and getting tired of working on this thing.  It has been down for almost two
months due to this problem!  Thanks for any help!
