OK got the supra running. But the down side it will only run when shooting carb cleaner in it. SO are the injectors bad? thats my thought.
IwantMKIII;1597544 said:51 is not "norm". Its an improperly calibrated TPS. Take it off and check it, as your TPS is more than likely bad anyway if it hasn't been replaced before. Be sure it springs back to closed position easily and smoothly, if not the ECU will think you're giving it throttle when you aren't. This won't completely cause the car to stop working but it certainly won't help your issue. Also, even if the spring works, there still may be dead spots, its worth replacing if you haven't before.
