Here is what the CD says you should be seeing for a KAT engine as of 09-1987:
KOEO: 20 mA
20 seconds after start: 4 - 8 mA
60 seconds after start: 0 to -4 mA. At +20 degrees, the coolant sensor's resistance should be 2.3 - 2.8 kOhms
Temp at +80, fluctuating currrent reading, 230 - 290 Ohms resistance from sensor
My guess at this point is that your coolant temp sensor may be bad and is telling the brain not to enrich.
Good luck. Many posts on measuring EHA current.

Ok, thanks! :-)
Actually I think that the reistance of the coolant temp sensor is within that range, but I can always try again.
What do KOEO mean? Is it during startup?
I guess all of the current mesurments are is done when engine is started up from cold...
Thanks again!
