So I was never really able to figure out this code issue and my truck sat there since my last update, hence my absenteeism from the site. This weekend I picked up a ECU from an '87 4Runner with the 35070 ECU number and my original ECU is a 35130. The truck started and I had no check engine light anymore and I drove it around the block and it ran fine, although slow but I havent driven it in months so maybe I forgot how slow they are lol. I read the 87 and earlier trucks only ran the 1 wire o2 sensor and a different volt injectors, then in 88 they switch the low impedance or something so they ran higher in 88? I'm not too clear on that still, but the truck runs without any check engine.
What should I make of this? Anyone have a 35130 ECU I could test out?
