I have a 99 manual civic that i change the clutch, then after replacing the clutch, everytime i step on gas my shifter moves forward excessively with force, but if i step off the gas it will be back on normal please help what to do?

 

Check your engine mounts, specifically the one that goes from the rear of the tranny near the firewall.

 

thank you I got it fix now, you're right, its the mount
