    if it happens when you're ~1100rpm or lower then you're lugging the engine and in too tall a gear

    if it happens in any gear at any rpm during accel it might be the wheel is out of balance

    if it's when you're on it hard it might be torque steer/wheel hop lightly

      hmmmm.......

      sway bar bushings?

      axles? (that would be odd, but you never know)

      alignment way off?

      tire off balance?

      tire out of round?

      bent rim?

      fix code 101? (operator error)

                sway bar bushings are next to the steering rack, about 10-12" toward the center of the car from the wheel. They are a common Ion problem.

                    Hey Andy, maybe it's from backing into someone elses Saturn?? Oh wait, you said the front wheel lol!!

                    In that case than I must concur with the statement below;

                      nathan you might not be familiar with the ion rim design. on the 16's you need to use stickie weigts on the out side due to there being no lip. or you can static balance them on the inside. again i am almost 100% sure its not wheel related.

                        Almost 100% would be like 99.5% or 99.9%. So being 'almost 100%' is really like being 99.9% sure. Why can you just say I'm 99.9% sure rather than 'almost 100%' JFWY.

                        Check the lugs. See if they are loose.

                        Just my 2 cents.
