84 4KQ Injection help needed.

[Nate Stuart]

Did you check the 'spare' fuse in the side of the fuse panel? The car will run without it there (or blown), but not well (don't ask me how I know :).... It is the fuse that controls the CIS computer. Another quick check to see if the CIS ECU is operating is to pull out the FPR plug and see if the idle changes at all.

  I am seeking any input to possible problems on a family members 84 4kq.
  She had just left work (car started fine and ran great) and after driving it a few blocks (running great) it suddenly devoloped a problem.  It would barely idle and would not rev up.  She called me and I came right over.  It would barely idle as before and seemed to be running lean. So I unsnaped the airbox snaps and tried assisting the airflow sensor with my finger and was able to verify that it was definatly running quite lean.
    Decided to have it towed home and did some further testing.
  I initially thought that the fuel pump was bad, so I tested system pressure according to Bob (Mr. Bentley and I have gotten close lately) and the pump passed.
  Next test I thought of was to check the current through the DPR and checked my perfectly good running car for a comparison. Test OK.
    I need to get in and see if I can find anything more Bob has to say about the problem or suggested tests, but I wanted to get the request out to the list asap.
    TIA
