[QUOTE="singlespeed, post: 175796, member: 264"] For the cost of a can of carb cleaner, that may help if its just gummed up and sticky. If you end up replacing it, you [i]should[/i] get the ECU calibrated to the new one. So the ECU knows what feedback voltages actually relate to fully closed and fully open. Otherwise, the throttle butterfly position will be slightly off from the desired position. I doubt you would notice for fully open, as the last few degrees of movement would only allow a fraction more air through. However, at idle and very light throttle positions the change in airflow would be most noticeable as a small change in position will make a significant change in airflow. [/QUOTE]
