efi problem

[Graham Hughes]

Could you give me some ideas on a problem on a XF Ford 4.1 efi
manufactured 9/1987 using BOSCH EEC-1V injection.
The car up to now has been running well with normal maintenance.
Then it started to consume heaps of fuel and blowing black smoke like
an untuned diesel.
Took the car to Ford for investigation and they said it must be the
injectors need cleaning...this was done and the car was worse.
Ford said and was confirmed by a second injection specialist that all
the voltage inputs to the computer were correct and so the computer was
replaced but to no avail. 
The injectors should open between 2-10mS but on mine the minimium is
4mS.
It appears to me to be an input telling the computer to enrichen the
fuel mixture.......as the injectors are directly connected to the output
of the computer. Checking all wiring and vacuum tubes now.
After that I guess I'm lost.
 
Would be very thankful for any idears
