CEL code on a 91

[Zennsx]

Can anyone help decipher a CEL code on my 91, it is exactly as follows after shunting out the blue connector and turning the key to ignition:

1 short blink
4 long " "
4 short " "




2 short " "
4 long " "
4 short " "

It looks like that would be a code #44, which tells you there is a problem with the rear fuel supply. Maybe an injector - check your plugs for deposits/color on the rear bank (make sure not to overtorque the plugs on reinstall - 13 to 15 ft. lbs. I think).

How is the car running? Any hesitation under 4K rpm?

Larry,

Car seemed to be running fine other than a idle that was stumbling a bit.

First thing to do is disconnect the 02 sensors and go for a run. If the idle is fine with no stumbling, there you go.
When you do this you will throw additional codes (41 and 42). Disregard the CEL and drive it, see what happens.

HTH,
