hey all, me again. turns out my issue was a bad ECU all along but I've no idea which one to get. the ECU that came out of my car is an E8EF-12A650-A1C, and that option isn't available on rock auto for my vehicle. Is there another option for the '89 Escort GT, 5spd manual, with A/C and power steering? maybe the ECU that came out of my car was already the "wrong one"? Any help getting the proper one in would be amazing so the shop doesn't charge me $300 for a $100 item (still love those lads tho).
