Business ProfileforKamphaus Auto Care & Emissions

I brought my car into their shop due to a check engine light. The diagnosis came back that I have a catalytic converter misfire. The suggestion was to replace it with either an aftermarket model at a cost of over $1,000.00, or with an OEM version for thousands more. Being on a budget, I opted for the aftermarket option. After the part was installed, and I was ensured the problem was now resolved, the check engine light came on again. I had to bring it back for inspection. I was informed, after all of this, that due to the emission standards on my vehicle, that the aftermarket converter, which was tested and performed as it should, was not qualified enough to satisfy the emission standards, and that my check engine light would intermittently come on and off. I am now at a point that I need to get an emissions test done so I can get my license plate sticker, and my car will not pass an emissions test. Why would a company knowingly give me an option to purchase something that does not work, unless they did not know themselves, which is concerning that any repair is properly diagnosed. I would like to get this part replaced with something that works properly, so I can pass my test and renew my vehicle with the state.
