I was driving my car from Youngstown Ohio to Cleveland Ohio on cruise, when all of a sudden my car began to lose power. Top speed was 45 mpr and idling very rough. I had my car checked because the service the engine light was on. I was told my catalytic converter was going bad. I had three coils in the back replaced and was told the other three needed replaced. HELP PLEASE!
What are the exact code numbers you have not code descriptions? I haven't seen that many coils go bad at once?Sounds like you have a plugged cat have a exhaust back pressure test done.

I do not know the codes, I was just told about both catalytic converter and coils. Will a clogged cat cause the power to drop?

Oh yeah you have to have good air flow going in and good air going out of the engine.A plugged cat can greatly effect how the engine performs. See if you have a nice blue spark from the coils that they say need to be replaced? If they do they don't need to be replaced.
