Catalytic Convertor Problems of Chevrolet Cavalier

The catalytic converter has been damaged and needs to be replaced. The repair shop says that the damage was a result of unburned gasoline going into the catalytic converter when the coil failed. The coil assembly failed and two cylinders stopped firing. I only drove the car about one-mile to the repair shop after the failure (which happened suddenly). The coil assembly had to be replaced at a cost of about $400. After it was replaced, the "check engine" light came on and the repair shop says that the on-board computer diagnostics indicates that the catalytic converter has failed. The car cannot have its registration renewed without a functioning catalytic converter, which will cost about $500 to replace.

Ets and check engine lift on all the time. From the time that I purchased the car these two lights remained on. The car would lose power while I was driving causing me to be left in the middle of intersections and traffic. I took the car back for repairs numerous times to the dealer and the seller and to various car repair places. But, no one was able to find the problem and repair it. A few years ago - I took my car for repairs to another chevorlet dealer and they told me that it was the catalytic converter. And that it would be cheaper to have it replaced tby someone other than a dealer. So, I took my car muffler repair and had it replaced (at a very expensive cost). The lights did not go off after the repair. I was told they had to be re set which they could not do. So, I took it to a car repair place and had the lights reset. It seemed to fix the problem. Now, a year or so has gone by and the lights came back on. A few months later the car started to lose power again and I took it back to the muffler shop - they could find no problem . Again I took it to a repair place and had the lights reset. At this time the lights have remain off, but the car still loses power off and on.
