My mechanic reconditioned 4 of my fuel injectors and coded them correctly but the car is running very badly now and he thinks it is a ECU problem and it needs to be brought to the nissan dealer to have the ECU rebooted ? Do you think this could be the problem ?...can a fuel injector change affect the whole car's computer system ? Thanks Barry
