Okay everyone, I have a 2009 nissan altima coupe 2.5s with cvt. I am about to reach 200k this coming weekend. Is there anything I can do to prolong my engine life. I know she doesn't have as much power from when i first got her. Should I look into getting a new engine or do an engine rebuild. Also, does anyone know where I can get the rebuild supplies if they even exist. Someone please help me. I want to make sure she can keep going for a long time. Oh my car shakes when i am at a red light, I read it might be caused by the autozone alternator something about having sub par cluthes. I have new engine mounts so I know that isnt the problem.
