I have a 1990 Honda civic SI. I believe it is a cable clutch, Latley it has been slipping worse and worse in first gear. Some times it is so bad that i really cant accelerate for $*!%. I would think this means it is going out on me but some time it grips great so i am very confused. I'm not hearing any wierd sounds or grinds, Just geting bad slip some times. Is there any way to tighten my clutch? my mechanic told me it is self adjusting. Thanks if there is any way to tighten my clutch i would really appreciate the advice.
