I got a 1994 Honda Civic Coupe Ex.. I just got a brand new stock clutch put in my car but when i have the car on more than 20 to 30 minutes the clutch becomes hard to push down and when i try to take off the clutch picks up high and then it starts sliping.. I had this problem before but i thought it waz that the clutch waz gone. But then i put a brand new clutch in my car i though it waz going to be good.. But the clutch still slips when its on for a long time.. If anybody knows what i should do or whats the problem please hit me up..... Thanks!!
