It was really pricey. Not sure the info they told me was correct, At first they said that my car was misfiring on three cylinders, and it must be the coils, I told them I just had them replaced then they said it was the plugs which I just had replaced then they said I had the wrong plugs. I feel like for $140 to diagnose the issue they could have looked at the coils and found that they were new. Also I have had a vehicle misfire before and I never felt the car misfire. And when I took it back to the shop I had the plugs put in, they said they could not find the misfire engine light report and it should have been there if it was misfiring. Then the other issue that pulled on my car a small emissions leak they said I need to pay them more to diagnose that. I feel like they may just see me as someone they can take advantage of, but I could be wrong.
