I am forever grateful to 180. My car suddenly started to not accelerate properly and it would not go over 35mph. I brought it into the mechanic and they said one of my cylinders was misfiring, so they fixed it. After that, they said it still wouldn't accelerate. The discovered that it was the catalytic converter. They didn't charge me for the work they had done and they referred me to another place that could fix the cat for cheaper. I'll never go anywhere else for my car services.
