Clutch weirdness...
 

Whenever its in mid day and I turn on my ac 3-4 and then try to take off it feels as if my gas pedal doesnt work the same at allll. I go to 1.2k and start off and have to gas it till the pedal hits bottom for the car to take off smooth, and even then its rough... what could this be? Also my gear changes are weird. When ever I pop it into 2nd it does a bang... I almost have to wait for a second in neutral before going into second and I have to do it smoooothly. Do I have a clutch problem? Transmission? anything sounds familiar? I know this is a big subject and it can go many ways, but I was hoping there is a big symptom teller anywhere... thanks!
