    1jz fuel cut at low boost after engine swap

    I have figured out what was wrong with my car, i had a ground wire pinned wrong in the ECU harness. I overlooked it so many times so check yours to be sure they are in the correct spot.

    1jz fuel cut at low boost after engine swap

    Hey there, did you figure out the problem with the car as yet. I'm having the same prob only diff is i pulled codes for TPS, MAP Sensor, W/Temp, Air Intake Temp. I have replaced the W/temp and TPS and the codes still remain. Let me know the outcome. Mine is a JZA70 with stock ECU.
