So I installed a new Fx100 on my 2013 honda civic si. After sending it out to be Installed I received the vehicle back with symptoms of it still somehow slipping. The clutch pedal felt funny. Ex it was good in pressure towards the top but once you got to the bottom it felt like I stepped in a pile of marshmallow. When I would take off the clutch would barely come back up. I somewhat helped it by pumping the clutch pedal multiple times and got full pressure on my clutch pedal while disengaging. Unfortunately the real problem was still occurring. When I would step on the accelerator to accelerate my rpms would jump but my vehicle would just jerk and barely catch up to the rpms. Could this mean my clutch was Installed incorrectly? The clutch was brand new and reviewed by me for any possible defaults in the clutch itself. Is it also possible that I may had burned my nee clutch already since the revs went up higher than the vehicles speed? Could this be maybe they forgot to resurface the fly wheel or adjust something within the kit? Im looking for any possible possibility that could had caused this. I spent money on my clutch and installation already. I dont want to have to do it twice...
