Subaru Impreza stw 2.0l 1996. Sometimes when I try to accelerate rapidly, 2-3 gears mostly, rpms raise fast but no increase in speed. If I step on gaspedal slower it accelerates like it should. It has almost 185k miles (300000km) in meter. Does this symptom apply to slipping clutch and if it does, is there any remedy prior changing clutch. I'd like to wait till winter is over and then do the the clutch change so I dont miss any wintertime fun. =)
