The past few days, it's been around low 40 degrees in my city. Feels like the engine is working pretty hard to start itself when I turn the ignition. Tonight, after watching a movie at the movie theater, I came back out and started up the engine. As I was driving, felt as though I had somewhat of a loss of power/acceleration when I step on the gas. The clutch also feels smoother than usual when I let go of it after switching gears. It hasn't felt like this AT ALL until this point. Is it a bad clutch that may have to be replaced?

Then, I got home and turned off my engine on my driveway. Several minutes later, I tried to start it again and it did not turn on. All the lights were on as usual at the "on" position of the key. However, when I tried turning the ignition, there was a clicking sound with the lights flickering as well. I figured the battery might be dead so I jump started it and it worked. However, it still feels like the clutch is slipping or something with the loss of power.

Are these two problems related? What do you think the problems are?
