Q: My car is having issues. Can you try to help me ?

asked by on August 18, 2016

I have a 2007 Mazda CX-7 and it's making a weird noise when I hit the gas. I'm thinking it might be the camshaft sensor. It also blows smoke out of the muffler from time to time. Also, when you step on the gas it takes a while to speed up.

My car has 154 miles.
My car has an automatic transmission.
