I have done extensive work and many of hours testing, rewiring and troubleshooting this issue with my single turbo 1jz. I keep getting a code 31 for the airflow meter circut and a tps code, I fixed the wire for the tps then it went away and now its back. So i believe that i have another wire issue or the sensor itself is bad. However I am unable to source the air flow meter code, I bench tested the map sensor and swaped sensors with a buddy and still having these bugs.
The engine cranks right over and fires up then runs really rough. I changed ECU's and even had the capacitors replaced in the one, so that's not an issue. I also went over the entire wiring harness and I'm out of ideas. Looking for some outside assistance. car has been down for seven months, please help. sorry for the long, word filled post lol.
