Hey there so i recently purchased a 2010 chevy HHR with 270,000 miles. Its a decent runner but ive noticed that compared to even my gf's 02 impala the acceleration is not great. Ill be trying to go up a slight hill and have to push the pedal way more than i should be needing to. Its like it doesn't get enough power until i really give it gas. Really new to cars and taking care of them so all help and advice is greatly appreciated. I can also take a video of my car accelerating if you guys need. It seems to be shifting good though not too rough. Also ive noticed that the steering wheel shakes a little bit when i get up to higher speeds. Not terrible shaking but enough to feel and hear it.
