It could...remember the old car radio volume knobs (and Yamaha receivers)? They would develop some wear/corrosion or something that interfered with the electrical signal at a point or two. But you should also look for vacuum leaks around the throttle bodies too. Another thing that we've noticed happening is a small ring of crud that builds up around the throttle body where the butterfly meets the side wall (presumably from the crappy EtOH laden gas we're forced to use). This can leave you with some erratic performance at very low throttle openings. You can remedy that easily by spraying a rag with carb cleaner and wiping out the inside of the TB.
