Just replaced injectors on 78 prado with the 1kzte, and there was a loud pinging and excessive smoke. Took injectors back out to inspect and make sure they were seated right, and one injector has excessive carbon compared to the others. made sure the injector seats were clean of debris and reinstalled and the pinging is still happening. Bled the injectors and no difference. Could it be a bad injector from factory? bad injector seat washers?
