One day I was driving my car home making a right turn and my engine started making noise and was acting as if it was going to cut off. So I parked my car called my mechanic he came over and looked at the car I said it could be a possible rocker arm that has gone in the car or I could have something to do with the check engine light coming on giving me a code for a cam positioning sensor / solenoid. Also when I purchase the car not too long after me driving I noticed there was some noise coming from my back tires. I couldn't figure it out for a while until one day I looked at my tires and noticed that on the inside there was a considerable amount of scraping going on wearing away my tread. It would always seem to happen when I got new tires on the car so I thought maybe the tires were too big for the car but I ordered what the manufactor suggested the tire size should be for the car. So I had a tire specialist look at it and an alignment specialist look at it and they told me that the suspension springs may be causing my issue. They said that I should not have to change the size of my tire for them to fit because the manufacturer specifications are correct and the tires were the right size for the car.
