Friction? An electrical noise? Pardon me, I am not an engineer but please do shed some light on this "frictional effect" and the fact that it causes transmission of a certain "electrical noise" .
How does it relate to increased friction in the gas pedal? What is so serious about this noise that has such a massive impact on the drive-ability of the car that you're thinking to dump it?
Afaik, eliminating electrical noise from sliding mechanisms of such sort is not possible.
