My Fianée's has a sentra and the accelerator pedal is sticking.

I've heard from other people that all that needs to be done is cleaning either the linkage between the throttle cable and the throttle body with brake cleaner. Is this correct?

Is there anything else I should do or look out for?

 

Doesn't anyone have any comments/suggesstions about this

 

i feel mine get kinda sticky in the CLs once in a while...
