So I ve been having this wierd issue with my check engine light. At times it would come on real dim, get brighter, then turn off, come back on and so forth... I tried tracing the short or loose connection in EFI circut to no result... took the brains out today and took them apart and discovered black burn marks on the smaller of the two boards.... Ill try to post pics.
The ECU is 89661-2B290. I have a spare J-spec 89661-20750. But it seems to have a very different pin out. And some pins like THG, CCO, ACT are missing completly... Does anyone one know what those are? Do I need them? Should I get a patch harness or re pin the ECU for it? What do you guys think? What are my options here?
