Hey everyone, i have a 1JZ Supra engine and stock 1jz ECU. I'm getting a CEL when the ign is on but when i connect the pins, the light blinks constantly. Intermittently when i do get codes, they would vary on different days. Ex: one day it would only be code 12, then another day it would be 13. I swapped the ECU out with another one and i was getting the same constant blinking. What could this be? Harness maybe?
Crazy ECU?
