Right now my ecu (90 gsx) has a leaky cap and shuts off once in a while so i purchased another 90 Ecu that has been rebuilt. After swapping them out i noticed that the new rebuilt ecu idles at 1200rpms and reads 52hz airflow according to my datalogger. I can only manage to get the idle down to around 900 if i lean out the afc 17% but my airflow reading is still around 45hz. My leaky cap ecu idles fine and only reads 27hz at idle. I also noticed that with the rebuilt ecu the iac doesn't move from 0 but with the leaky one it goes up and down just like its supposed to.
My first question is this rebuilt ecu junk? or is it maybe a 91-92 ecu?
What if its a 91-92 ecu and i didn't switch pins 6 and 14 would the car even run?
The part number on my leaky ecu is MD145903
and the rebuilt one is MD128625. I understand the rebuilt one is a fwd but does that make a difference?
Is there any way i could tell if the shop that rebuilt this ecu used a different year circuit board than the part number states on the case?
Any help would be great.
Thanks
