Limp mode cutting throttle after start MANUAL SWAPPED
I have a 2002 IS 300 it was converted from auto to manual by the previous owner. I believe it still is running an auto harness, but it does have a manual ECU from Royal tuned the car after start up only on very random starts will cut throttle and RPMs completely like it’s going into a fail safe mode. I have a. Throttle body lock so full cable throttle and I mash the gas and it does not react at all. The only way to get rid of it is to basically key bang the car so it resets all the control units and it is perfectly fine no issues at all after that the car has all four wheel speed sensor codes so I’m guessing there’s an issue with the wheel speed sensors communicating to the car. It does not read speed but everything else works. I will attach screenshot of codes. The car is throwing any help would be much appreciated.
